B.A 6th Sem:- Geography || One Shot Class ||

Hello, welcome dear students and dear friends. Once again, a warm welcome to all of you. As always, in the most important class under "Me and My YouTube Class," and as you dear students all know, this is a final important class for the students of your Sixth Semester Geography. You must have understood what "final important" means; after this class, there might not be any more Geography classes because the entire syllabus will be completed. Clear? So, I dedicate this final Geography class of the final semester to you, and I hope that whatever we have taught in Geography will be useful to you. You will learn from this class. See, I want to tell you one thing regarding all the classes I am taking: please do revise. Please do revise. Because you understand the class after watching it once, right? Absolutely, because we know from feedback reviews. But what happens is that when you go to the exam, you forget those things. That's why I say, please do revise. Clear? So, a very warm welcome, congratulations, and greetings to all the dear students who have joined live. Greetings from Bharat Sir. Now, today, we will not only clear Unit Fifth but also provide something special later. That's why it's called a "One Short Class." Okay? So, let's move towards the important class. Dear students, first, let's clear Unit Fifth thoroughly, and today the background color is different because students say that they have some issues with the white color, they don't understand, or their eyes can't focus much. So, no problem, with the background color, meaning the background behind, you will be able to understand comfortably. It won't strain your eyes. The entire class is being made according to you. Okay, Namaste, Radhe Radhe to all of you. So, dear students, here we will talk about the fifth unit. First of all, we will talk about Unit Fifth, and then at the end, I am going to tell you something magical and important. That's why we call it "The One Short Class." Okay? First, let's talk about the topic: Rail and Water Transport. Rail and Water Transport. Let's talk about rail transport. You already know about rail transportation because humans utilize and use trains the most for their economic activities, and this is economic geography, which is based on most human activities. Therefore, this becomes an important question. Clear. Namaste, Bharti Malik. See, rail transport is the most efficient means of carrying heavy goods and passengers over long distances on land. So, you need to keep this in mind. From the perspective of college exams, I have written that I am explaining two important aspects from the perspective of college exams. I am telling you myself which one is important. Now, see, the first is Transcontinental Railways. Transcontinental means these are railway lines that pass across the entire continent, connecting the two shores, both the western and eastern shores. Their economic and diplomatic importance is very high. Among these is the first important one that can come in the exam: the Trans-Siberian Railway. Regarding its extent, it is the longest and most important railway line in the world. The question comes. It will be formed from here. It starts from St. Petersburg, the capital of Russia in the west, on the Baltic Sea, and goes to Vladivostok port on the Pacific Ocean coast in the east. So, what is the world's largest railway line? Trans-Siberian. Where does it go from and to? It is important to know this first because if we talk about its total length, it is 9289, 9282 kilometers, and it has major stations like Moscow, Kazan, Yekaterinburg, Novosibirsk, Irkutsk, and Chita. Most of the stations are in Russia, so it becomes very important in itself. The question about Trans-Siberian might come, even if it's a short one.

Further, what is the economic significance of this railway line? See, it has opened up economic routes in the cold and inaccessible region of Siberia, Russia, meaning it has created a path for development. It has helped in transporting timber from Siberian forests, coal, iron, and other minerals to the industrial centers of European Russia. Because the natural resources are transported through this train to the needy and essential industrial institutions. This route directly connects the Asia-Pacific region with European markets. Now, if we talk about the second railway line, it is the Canadian Pacific Railway. Its extent: this railway line connects the cities of Halifax and Saint John on the eastern coast of Canada with the port of Vancouver on the Pacific Ocean on the western coast. So, what was the objective of its construction? Regarding the objective of construction, its construction was developed in 1886 under an agreement to include British Columbia in the Canadian Federation. So, it has significance, of course, because it is called the economic lifeline of Canada. Most of Canada's economic transformation and transport happen through this. Second, this railway line transports a large quantity of wheat produced in the prairie regions of Canada to the ports on the Atlantic and Pacific coasts, from where it is exported. So, you should note this down; it is very essential and important. And besides this, it is also known for the transportation of meat, timber, and pulp.

Then, let's understand railway lines according to regions. Let's talk about regional railway lines, according to area, which includes the first one: Europe's rail network. Considering the density, Europe has the densest rail network in the world because almost every corner of every country here is connected by railway lines. The second characteristic is that it focuses more on passenger transport than freight trains. But if we talk about our India, freight trains are the ones that earn money; passenger fares and passenger tickets are not that profitable for Indian Railways. Clear? Moving on, yes, Namaste ji. First, keep watching the class and understand. Sir, my practical exam file is also not made. Then make it, brother, make it. High-speed trains like France's TGV and Germany's ICE are very popular in these regions. Regarding international connectivity in Europe, trains like Eurostar connect London (UK), Paris (France), and Brussels (Belgium) through tunnels built under the sea. So, these can be called high-speed railway routes.

Next, let's talk about North American railway lines. Looking at the characteristics, unlike Europe, in North America, especially in the USA and Canada, railway lines are used for heavy freight transport. Passengers use airplanes for long-distance travel. It is different from Europe here. Regarding operations, the railway network here is managed on a large scale by private companies, meaning it is on private contract. It connects agricultural areas and minerals to industrial cities and ports.

After railway lines, comes oceanic waterways. You must have understood the meaning of oceanic waterways because, for the most part, heavy resources that are transferred from one country to another are done through ships. Right? So, more than 80% of international trade transportation happens through international waterways because it provides the cheapest transport for heavy goods. Regarding major ocean routes, let's see: North America, Atlantic, and Europe. Between these comes the Panama Canal, and on this side comes the Suez Canal. Right? In relation to this, the Panama Canal means the Pacific Ocean, the Suez Canal means the Indian Ocean, and Asia. So, large-scale transportation of 20-20 ships from these large oceans and continents takes place.

Now, let's talk further. Let's talk about the North Atlantic Sea Route. See, this route connects the industrial areas of northeastern United States and Canada with the developed countries of Western Europe. If we talk about its characteristics, it is called the "Great Route" or the busiest sea route in the world. The busiest sea route in the world is the North Atlantic Sea Route. Remember this. This question can come. Right? Yes, Sixth Semester students can give the CET exam. If it's a Fourth Semester exam, then prepare. Tell me the important long-answer questions, sir. Oh, Harsh, as soon as the fifth unit ends, you will get something super special. It will be useful to you, what you are demanding. And yes, all the content, whatever I am teaching you, is uploaded back on our app. Classes will be uploaded back on the chat app as soon as this class ends.

See, now let's talk. About 25% of the world's foreign trade alone happens on the remaining waterways. Now, talking about this route, on both its shores are located the world's most developed industrial and technologically advanced nations. Because of this, there is a heavy exchange of manufactured goods, chemicals, and raw materials. Then, the Suez Canal Waterway. Let's look at its geographical location. Suez is a man-made waterway located in Egypt, which connects the Mediterranean Sea to the Red Sea. It was constructed in 1869. Regarding its importance, the construction of this canal reduced the distance between Europe and South Asia by 7200 kilometers. Because earlier, ships had to go around the African continent, around the Cape of Good Hope, and then go. But now, with the construction of the canal, direct transportation has become possible. Regarding trade, through this, minerals from Central Europe, spices from Asia, and clothes and machinery from Europe reach the traders.

Next, let's talk about the Panama Canal Route. If we look at its geographical level, it is a canal built across the Isthmus of Panama in Central America, which connects the Atlantic Ocean to the Pacific Ocean. It was constructed in 1914 by the USA, the United States of America. Further, talking about its characteristics, this canal is not level. This canal is not level because it uses a lock system, a water passage system, to cross mountains. Where ships are raised and lowered along with the water level. Regarding its importance, it reduces the distance between New York (East Coast) and San Francisco by approximately 13,000 kilometers. It gives flow, meaning speed, to trade between North and South America.

Further, yes, see, Inland Waterways. Now let's talk about the use of rivers and lakes for transporting goods and passengers within a country, which is called inland waterways. Right? And it is called inland waterways. So, in this, let's talk about Europe's inland waterways. The first is the Rhine Waterway. Understand the Rhine Waterway. This river originates from the Alps mountain (Switzerland), passes through Germany, and falls into the North Sea near Rotterdam port in the Netherlands. Why is it important? Because it is the busiest inland waterway in the world. Note this down. It passes through the Ruhr region, Germany's largest industrial and commercial area, where large quantities of coal and iron are found. For this reason, it is also called the "Coal River." It directly connects the industries of Western Europe to the sea.

Next, let's talk about the new inland waterway, the Danube Waterway. This river originates from the Black Forest region of Germany and flows through many Eastern European countries like Austria, Hungary, Serbia, Romania, and falls into the Black Sea. Regarding its importance, it is an international waterway primarily important for the transport of agricultural products, grains, and raw materials. However, its industrial use is slightly less compared to the Rhine because it does not directly open into open oceans. In this way, there are also major waterways in the former Soviet Union. First, the Volga Waterway. Regarding its characteristics, the Volga River is the longest river in Europe and flows through the industrial heartland of Russia. What is the challenge in this region and what is the solution? So, see, this river falls into the Caspian Sea, which is a landlocked lake. To overcome this problem, the Soviet Union constructed the Volga-Don Canal, which increases the water flow and allows for expansion. Clear?

Now, understand further. See, the importance of this canal system is that the Volga River has been directly connected to the Black Sea, the Baltic Sea, and the White Sea. Now, through this, timber, petroleum, and grains from the interior regions of Russia are easily transported to the seaports. Meaning, to be honest, the last unit is not at all burdensome; it is very easy, as much as you understand. Kailash Dhan Sir, thank you. Because of you, these three years have passed so well. That's great. When you look back in life, you will definitely remember us. And the marks added to your mark sheet are for a lifetime. So, whenever you look at your mark sheet and see the percentages, you will surely smile remembering the "Mind of Class."

Now, let's talk about Air Transport. Air transport is the fastest, modern, and highly scientific means of the modern era. It is best for long-distance travel and for transporting valuable and perishable goods. So, let's first look at the factors affecting air transport. See, the development and operation of air transport depend on several geographical, economic, technical, and political factors. So, in exams, you mainly need to remember these in five points. How many? Five. See, first is geographical distance and diplomatic position. Air transport is directed by this because it is necessary for countries or cities located intermediately between two large continents or trading regions for the flow to be high. They become major air hubs. Airplanes have to stop for refueling and maintenance during long-distance flights, so depots are also necessary. For example, Dubai and Singapore have become the world's largest international air hubs due to their excellent geographical location, connecting the East and West. Clear?

Now, further, see. The second factor that influences the position of aircraft is weather and climate. See, visibility. Because the safety of airplanes is directly related to the weather. Excessive fog, low visibility, heavy rain or snowfall, or cyclones cause major disruptions in flights. What should be the ideal conditions, dear students? So, in regions where the sky is clear throughout the year and the weather is calm, air transport develops rapidly. Tropical and subtropical regions are more conducive to this, where airplanes can fly well. Whereas in polar regions, flights are often disrupted due to bad weather.

Next, economic development and capital also play a crucial role. Because it is highly capital-intensive. The construction of airports requires enormous capital. Modern aircraft need to be purchased. Establishing runways and air traffic control systems is a very expensive task. It requires heavy investment. It is said to be very easy and fast transport. But it is also the most expensive. Moving on, purchasing power. Because the fare for air transport is much higher compared to other means like rail and bus. Therefore, its use is more prevalent only in those countries or regions where people have a high standard of living and can afford expensive tickets. This is why it has developed densely in Western Europe and Northwestern Europe. By the way, let me tell you a reality. I have been so immersed in this field of education that I don't even know that I should also travel somewhere. I am telling you the truth because when transport came up, the idea of traveling came to my mind because I have never traveled by airplane to cover a distance. You will say, "Sir, really?" Yes, it's like that.

Further, see, understand technical and infrastructural facilities. From the perspective of scientific progress, the development of modern jet engines, radar systems, satellite navigation, and night landing techniques has made airplanes safer and more efficient. Regarding maintenance capability, regions that have high technical skills and good facilities for aircraft repair are at the top in this sector of aviation. So, see, moving on, next, among the factors affecting air transport is government policies. Because, see, transport happens only when the government issues it. Politics is involved behind this. There is also an economic reason. See, aerial sovereignty. Because according to international law, the sky above each country is its sovereignty. Meaning, if it is India, then the entire sky above India is under India's authority. No foreign aircraft can use a country's airspace without permission. Open skies policy. When the government adopts a liberal policy, it brings more international commercial flights. War or political tension, like during the Russia-Ukraine war, airspace is closed, due to which aircraft have to take long detours, and costs increase.

Now, let's talk about the world's major air routes. So, understand. The distribution of air routes at a global level is highly uneven. More than 60% of the world's air routes are concentrated over the industrial and developed countries of the Northern Hemisphere. The world's main air routes can be divided into the following three categories. First, North America, the North Atlantic Air Route, and third, Europe. So, see, the Trans-Pacific route is here. And from this side, the Europe and Asia route. In this way, they connect back with East Asia, Japan, and China. So, now understand. First is the North Atlantic Air Route region. This route connects Eastern North America, mainly the USA and Canada, with the countries of Western Europe. Which one? The importance of the first one is that it is the busiest and densest air route in the world, the North Atlantic Route. Regarding major hubs and airports, which ones are included? New York, Chicago, London, Paris, Frankfurt, and Amsterdam are major, big cities that are included. Why? Because on both sides of the Atlantic Ocean are the world's wealthiest industrial and commercially active countries. So, there is a high movement of business travelers, businessmen, and high-value cargo like electronics and medicines, which leads to this high traffic.

Further, let's talk about the Europe-Asia-Australia Air Route. Regarding the nature of the second route, this route starts from Europe (London, Paris), passes through the Mediterranean Sea and the Middle East, and then goes to South Asia (India), Southeast Asia, and finally to Australia. Regarding its importance, this route is the main distance connecting Europe to the emerging markets of Asia. Regarding major intermediate stations, it connects countries and cities like Rome, Cairo, Dubai, Mumbai, New Delhi, Bangkok, Singapore, and Sydney. Its characteristic is that Dubai and Singapore, airports located on this route, have become the world's largest refueling and transit airports, where there is a lot of traffic coming and going.

Next, let's talk about the Trans-Pacific Air Route region. Crossing the Pacific Ocean, it connects the western coast of North America with the countries of East Asia. Its importance: in modern times, the economic superpower status of East Asia, especially China, Japan, and South Korea, is due to this air route. Regarding major hubs, Los Angeles, San Francisco, Honolulu (Hawaii Islands), and as main refueling stations in the central Pacific, Tokyo, Shanghai, Hong Kong, and Seoul are prominent. If I ever get a chance to go to Antarctica. Yes, I would definitely like to see the things in the world that...

Unique and where people wish to go. So if it is written in destiny, we will definitely go. Let's talk further about international trade. Look at the next topic, the exchange of goods, services, and capital between two or more independent countries in a free and legal manner is called international trade. This is the main basis of the modern economy because no country is completely self-sufficient. Let's talk further about the basis of international trade. On what basis does trade happen? So, see, what is trade? You know this because countries transact with each other. We will read the main reasons for this in five points. How many reasons will we read? Five. First, variation in national resources. Because the distribution of natural resources on Earth is highly uneven. The geological structure and terrain are also uneven. Some places have more resources, some have less, some don't have any at all. In this way, the geological structure determines which minerals will be found in which country and region. For example, the Gulf countries have a large amount of mineral oil, while Australia and South Africa have rich gold and diamond reserves. Therefore, mineral-rich countries export to each other. Those who need petrol buy petrol, and those who need gold and silver, all cooperate with each other. Clear? Look further. Understand climatic factors. Climate directly affects a country's vegetation, crops, and agricultural production. Let's also talk about the diversity and specificity of crops. Countries with tropical climates like India, Sri Lanka, and Brazil produce large quantities of tea, rubber, spices, and coffee, respectively. In contrast, countries with temperate climates like Canada and America are ahead in the production of wheat and dairy products. So, due to this climatic variation, agricultural products are traded internationally. So, the next factor influencing international trade is population, because the size, density, and culture of a country's population also determine the nature of trade. Cultural factors within population: In some regions, a specific type of art and skill has been developed generation after generation. For example, Chinese silk, porcelain, Indian handicrafts, cotton textiles, and Persian carpets become the basis of trade worldwide due to their cultural uniqueness. Then the size of the population also determines this, because in densely populated countries, most of the manufactured goods are consumed internally. For example, in countries like India, imports are high and exports are low. Conversely, in less populated regions, resource-rich countries like Canada and Australia export on a large scale. Let's understand further. Understand the stage of economic development. See, the level of industrial and economic development also varies in different countries. This also determines the traded goods, because trade is higher where there is demand and where there is supply. Look at industrial countries, developed nations like Germany, Japan, USA trade in advanced technical machinery, automobiles, and electronic items. Developing countries, which are primarily agricultural, mainly export raw materials, minerals, ores, and agricultural products, and buy back manufactured goods. In this way, transportation and communication also affect trade, because international trade cannot be imagined without efficient transportation. Technology is necessary for this. Because in ancient times, along with transportation, transport was also limited. Therefore, only valuable goods like gems and silk were traded over long distances. But today, in modern times, with the invention and development of refrigerated ships and large containers, perishable goods like milk, meat, fresh fruits, and vegetables are sent to different corners of the world. Let's talk further, there are also obstacles in this trade. What are the obstacles in international trade? To protect domestic industries and stabilize the country's currency, governments impose various restrictions and barriers on international trade for political reasons. We will mainly read this in two parts. America repeatedly asserts its dominance over international trade by imposing tariffs. So, what are the trade barriers? One is tariff barriers, meaning import duties and customs duties. The second is non-tariff barriers, which include strict rules and restrictions. So, let's first talk about tariff barriers. This is the most common form of trade barrier, because under this, the government imposes customs duties on imported foreign goods. If the duty is high, the goods become expensive. Thus, the effect will be that due to the tax, foreign goods become expensive in the domestic market. This forces citizens of the country to buy locally made products, which supports domestic industries because domestic goods will sell. What are non-tariff barriers? In this, taxes are not imposed, but trade is controlled through rules and laws. Strict rules are made, meaning quotas are set, because the government fixes the maximum quantity of a particular commodity that can be imported in a financial year. For example, this year, only 5 lakh tons of edible oil have been imported into the country. These rules are made to maintain trade balance. In this way, there is also an embargo and complete prohibition. Second, political security. Due to situations like war, when a complete legal ban is imposed on trade with a country, as was imposed by the US on North Korea and Iran. Currently, there is also a war, so there is a complete ban on trade. Health and sanitation standards also affect trade, because developed countries often stop agricultural products from developing countries by saying that they contain high amounts of chemicals or pesticides. This is also a way to stop trade. Big countries say that the goods coming from small countries are inferior. We don't like them. Because of this, trade becomes a bit difficult. Clear? Yes, hello. Look further. So, let's look at the pattern and trend of world trade. In the present time, there have been major changes in the direction and information of the global trade structure. Understand the main features of the trade pattern in the modern world. First, a huge increase in the volume and value of trade, because today the trade pattern has changed. What is the reason? A huge increase in the volume and value of trade, because the pace of international trade has been much faster compared to global GDP. Due to the efforts of globalization and the World Trade Organization, trade barriers between countries have opened up, leading to a manifold increase in the total volume and monetary value of trade. Second, the nature of traded goods has also changed. Because in the past, primary products like raw materials, oil, coal, and minerals dominated world trade. But currently, these are not so important, because manufactured goods like smartphones, computers, automobiles, and chemicals are traded the most. Along with this, the share of services trade like information technology, software, banking, insurance, and transportation is rapidly increasing in the global market. So, next is the change in the direction of trade. Because until the latter half of the 20th century, global trade was mainly spread across the North Atlantic, Europe, and North America, and most of the world's trade happened between and through these countries. Understand further. Look at modern science. Currently, the direction of trade has shifted towards the Asia-Pacific region. That is, trade also has its identity over time. China is emerging as the world's largest exporter. India, South Korea, Brazil, ASEAN, etc., have now become new centers of global trade. This is called the shift from West to East in economic geography, which is changing the hub of trade. Regional trade blocs have also emerged. Because a major pattern of modern trade is that neighboring countries are forming trade organizations among themselves so that they can trade without any barriers or taxes. For example, ASEAN, SAARC are groups of some countries that have become global hubs as trade alliances. For example, the European Union, USMCA (America, Canada, and Mexico's new NAFTA), RCEP in the Asia-Pacific region. Besides this, you all know that India also has SAARC. Besides this, ASEAN is also a service association. Let's talk next, so you must have understood this much. Now, as I said at the end, I will do something special and amazing. Okay, dear, so now look, as I said, at the end, I will give you a complete revision dose of all five units, and that dose is a model paper. I am putting important short questions from all five units in a model paper, and long questions. So, while going, definitely prepare this model paper. You will remember while giving the exam that sir gave a bombshell at the end. Look, this is the last and best model paper regarding economic geography. You know the exam will be for three hours and 80 marks. So, look, section A will have very short answer questions, 10 of them, which you have to answer in 30 words. Define economic geography. This will be the first question, most likely, whether it comes in big or small. See, economic geography is that branch of human geography which studies the regional variations and spatial patterns of human economic activities like production, exchange, distribution, and consumption on the Earth's surface. First important question. Will you take class tomorrow? I don't think I need to take class tomorrow because I will complete everything today, five units, a combo model paper that will create a stir, so I think it's definitely worth it. Look further. Second question: Resources are not made, they are made. Who said this statement, and what was its reason, what is its meaning? So, see, this famous statement is by economist J. Zimmerman. Its meaning is that no element present in nature becomes a resource until humans learn to consume it according to their intelligence, technology, and needs. Similarly, a tremendous third question is to state the main characteristics of plantation and garden agriculture. Plantation or garden, plantation means planting agriculture, like rice, I think it falls in this category. So, see, this is a commercial and monoculture agriculture called plantation agriculture, in which crops like coffee and rubber are grown through plantation activities in large farms and plantations. And it requires a large amount of capital, modern technology, and skill management. Fourth important question is why regur soil is best for cotton cultivation? Because regur black soil has a high capacity to retain moisture for a long time and is rich in iron, lime, and magnesium. Therefore, cotton plants benefit directly. Fifth important question for you is tremendous. So, see, differentiate between traditional and non-traditional sources of energy. So, see, what are traditional sources? Like coal, petroleum, because they are limited, and they have been used traditionally, which are now ending and also cause pollution. Whereas non-traditional sources like solar energy, hydroelectricity are unlimited and new energy sources, and they are also environmentally friendly. Next is copper. Write two main industrial uses of copper. It is possible that iron or magnesium might come here instead of copper. This type of question will come. See, due to copper being a highly conductive material, its main use is in electric wires, cables, and electronic devices. Second, copper is also used in making alloys like brass and bronze. Next, question number seven is important. For which industry is Germany's Ruhr Basin famous? Germany's Ruhr Basin region. So, Germany's Ruhr Basin is famous worldwide for iron and steel and heavy industries due to its rich bituminous coal reserves. It is also called the heartland of Europe. Thank you, sir, your hard work will help us succeed. Absolutely, it should, shouldn't it? With so much effort. Bharti, thank you so much, sir. All your classes are a boon for me. Yes, very good. Next, which forests are considered ideal for the pulp and paper industry? For making pulp and paper. So, for this industry, trees from the temperate coniferous taiga forests are considered best, because the wood from these forests is soft and fibrous, which produces high-quality pulp and good paper. Next, let's talk about the Great Rock Way, which waterway is called this? I just read it today. See, it is called the North Atlantic Sea Route because it is the busiest sea route in the world. And it connects the industrial areas of the northeastern United States with the developed regions of Western Europe. Next short question is, what is a trade deficit? See, when the monetary value of a country's total international imports exceeds the value of its exports, that situation is called a trade deficit. That is, people in India order more and sell less, so this is a trade deficit. Clear? Now let's move on. PG Sir, thanks to you, three years have passed. They have become memorable moments of life. What a thing. Look further. Now you all know that in Part B, there will be long questions, and two questions will come from each unit. You all know this. Which you have to write in about 400 to 500 pages. I am talking about 12-mark questions. You have one day left. If you prepare them, you will definitely create a stir. So, see, from the first unit, the first question is to explain in detail the special areas and study methods of economic geography. This question has come for 12 marks. What are you waiting for? It is important to memorize it, and I have also explained it in the first marathon's Brahmastra. Second, present the classification of resources and discuss the need for resource conservation and the use of major resources. This has also been covered. Next, Unit 2. Discuss the geographical conditions, characteristics, and regions of extensive commercial grain agriculture in the world. For example, grains like tea and rice, wheat. A question might come from any one of these about their production conditions. Then, the second is the geographical conditions for the cultivation of sugarcane or tea in the world, such as temperature, rainfall, soil, along with the global production value. This is important. Next is Unit 3. Mention the types of iron ore in the world and explain the global distribution and production patterns. This question's answer is in Brahmastra number third. And explain the energy crisis and discuss the distribution, production, and international trade of petroleum in the world. Yes, in Brahmastra third. Then, from Unit 4, strong questions: Explain the reasons for the localization of the iron and steel industry and highlight the importance of the Great Lakes region of the United States. This question seems like a printout. It's 12 marks. Prepare it now. And let's talk about the next one, discuss the factors influencing the development of the cotton textile industry and shed light on the major manufacturing belts of Japan. Similarly, Unit 5, the final one. Present a comparative description of the Suez Canal and Panama Canal waterways and their importance in global trade. Either this is out, or it's going to be out like a 12-mark paper, or explain the main bases of international trade. Now, keep in mind, the 60-80 mark paper, 60 marks have been directly revealed by me. So, many short questions are formed. So, if you watch our five Brahmastra classes and look at the notes from the class, your exam paper will make your heart happy, and believe me, you have completed three years with faith. So, in this final time, make yourself better and create a stir. Definitely revise. Clear? Yes. So, my dear students, now you have one task, no, two tasks: first, revision, and second, send this class to all those students who have geography so that they can be helped and my hard work can be useful to all of you. Clear? Yes, Jai Shri Ram. Thank you, sir, your hard work will help us succeed. Absolutely, sir. My second-semester notes have been sent to your WhatsApp. Please check them. Definitely, definitely. Okay, so thank you so much, dear students and dear friends. Now we will meet in the next important class, which will be for a different subject for you, but for this, please remember it by heart. Jai Hind, Jai Bharat. Thank you, Vijay, and thank you so much, all dear.
