Direction: Read the case study given below and answer the questions that follow:Depending on the mode of occurrence and the nature of the ore, mining is of two types: surface and underground mining. The surface mining also known as open-cast mining is the easiest and the cheapest way of mining minerals that occur close to the surface. Overhead costs such as safety precautions and equipment are relatively low in this method. The output is both large and rapid. When the ore lies deep below the surface, underground mining method (shaft method) has to be used. In this method, vertical shafts have to be sunk, from where underground galleries radiate to reach the minerals. Minerals are extracted and transported to the surface through these passages. It requires specially designed lifts, drills, haulage vehicles, ventilation system for safety and efficient movement of people and material. This method is risky. Poisonous gases, fires, floods and caving in lead to fatal accidents. The developed economies are retreating from mining, processing and refining stages of production due to high labour costs, while the developing countries with large labour force and striving for higher standard of living are becoming more important. Several countries of Africa and few of south America and Asia have over fifty per cent of the earnings from minerals alone.What is the other name of surface mining?- a)Close-cast mining
- b)Open-cast mining
- c)Loose-cast mining

Saptarshi Ghosh answered |
Explanation:
People living in icy and extremely hot climates had to adapt to their harsh environments in order to survive. One of the most important ways they did this was through hunting. Hunting provided them with food, clothing, and other resources necessary for survival. Let's explore this in more detail:
Hunting in Icy Climates:
In icy climates, such as the Arctic, people relied on hunting to survive. They hunted animals such as seals, walruses, caribou, and polar bears. These animals provided them with meat, fat, and hides, which they used for clothing, shelter, and other necessities. They also used animal bones and antlers to make tools and weapons.
Hunting in Hot Climates:
In extremely hot climates, such as the Sahara Desert, people also relied on hunting to survive. They hunted animals such as gazelles, antelopes, and ostriches. These animals provided them with meat, hides, and bones, which they used for food, clothing, and tools. They also gathered fruits, nuts, and other edible plants.
Conclusion:
In both icy and extremely hot climates, hunting was a crucial way for people to survive. By hunting and gathering, they were able to adapt to their harsh environments and find the resources they needed to survive. While other activities such as weaving and herding may have played a role in some societies, hunting was a universal necessity for survival in these extreme climates.

Pragati Bajaj answered |
The Island on which Nomadism is based is Madagascar. Nomadism is the practice of moving from one place to another with no permanent settlement. Madagascar, an island nation located off the coast of Southeast Africa, has a long history of nomadic cultures.
Madagascar's nomadic cultures
Madagascar's first inhabitants, the Malagasy, were believed to have arrived on the island around 2000 years ago. They were nomadic people who relied on hunting and gathering for their sustenance. Later, the arrival of Arab and African traders and settlers brought agriculture and pastoralism to the island.
Madagascar's pastoralist communities
The arrival of pastoralist communities in Madagascar brought about a new form of nomadism. These communities were primarily made up of cattle herders who moved their herds from one grazing area to another. The Betsileo and Bara people are two examples of pastoralist communities in Madagascar.
Madagascar's current nomadic communities
Today, there are still nomadic communities in Madagascar, such as the Mikea people. The Mikea people are hunter-gatherers who live deep in the forests of southwestern Madagascar. They move from one area of the forest to another in search of food and resources.
In conclusion, Madagascar is the island on which nomadism is based, with a long history of nomadic cultures and current nomadic communities such as the Mikea people.

Jayant Mishra answered |
Spain and the United States invested heavily in coconut and sugarcane plantations in the Philippines. The Philippines is an archipelago located in Southeast Asia that was colonized by Spain in the 16th century. During the Spanish colonial period, the Philippines became an important center for the production of coconut and sugarcane, and these crops were extensively cultivated on large plantations.
Spain and the United States were two of the major powers that invested in these plantations in the Philippines, and they played a significant role in the development of the country's agriculture and economy. Coconut and sugarcane were important exports for the Philippines, and they contributed significantly to the country's wealth and prosperity.
In addition to the Philippines, other countries in Southeast Asia, including India, Sri Lanka, and Malaysia, also have significant coconut and sugarcane industries. However, Spain and the United States invested more heavily in the Philippines than in these other countries.

Rice needs water for evapotranspiration, seepage and percolation, as well as for management practices such as land preparation and drainage. Submerged rice cultivation practices help to promote water percolation and groundwater recharge, control flooding during heavy rains, and prevent weed growth in rice fields.

Shaft Mining
Shaft mining is a method of excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.
Explanation:
- Definition: Shaft mining involves the excavation of vertical tunnels to access mineral deposits deep below the surface.
- Process: Vertical shafts are sunk into the ground, and underground galleries radiate from these shafts to reach the minerals.
- Access: Initially, there is no access to the bottom of the tunnel, so miners have to use specialized equipment and techniques to reach the minerals.
- Equipment: Shaft mining requires lifts, drills, haulage vehicles, and ventilation systems for the safety and efficient movement of people and materials.
- Risk: This method is risky due to factors such as poisonous gases, fires, floods, and cave-ins, which can lead to fatal accidents.
- Application: Shaft mining is typically used when mineral deposits are located deep below the surface and cannot be accessed through surface mining methods.
- Importance: In countries with deep-lying mineral deposits, shaft mining is essential for extracting valuable resources and contributing to economic development.
In conclusion, shaft mining is a method that involves excavating vertical tunnels to access mineral deposits deep below the surface. It is a challenging and risky process but is necessary for extracting valuable minerals in certain geological conditions.

Divya Mishra answered |
Nomadism is a way of life that involves constantly moving from one place to another in search of food, water, and pasture for livestock. It is associated with several important regions around the world.
Three Important Regions Associated with Nomadism are:
1. Central Asia:
Nomadism is an integral part of the culture and history of Central Asia, which includes countries such as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The nomadic lifestyle of the region’s people is primarily based on raising livestock such as sheep, horses, and camels.
2. Sub-Saharan Africa:
Nomadism is also prevalent in many parts of Sub-Saharan Africa, particularly in the Sahel region. People in this region are mostly pastoralists who move their herds of cattle, sheep, and goats in search of water and pasture.
3. Middle East:
Nomadism has been an important way of life in the Middle East for thousands of years. Bedouins, who are nomadic Arabs from the desert regions of the Arabian Peninsula, have traditionally relied on camel herding, trading, and raiding for their livelihoods.
Therefore, nomadism is associated with three important regions - Central Asia, Sub-Saharan Africa, and the Middle East.

Jhum cultivation, also known as slash-and-burn cultivation, is prevalent in tropical regions of the world. Let's understand more about jhum cultivation and its geographical prevalence.
Jhum Cultivation
Jhum cultivation is a traditional form of agriculture practiced by many indigenous communities in the tropical regions of the world. It involves cutting and burning a patch of forest land to create a clearing for agriculture. The crops are then grown on the cleared land for a few years until the soil fertility declines, after which the land is left fallow for several years to allow for natural regeneration of the forest.
Geographical Prevalence
Jhum cultivation is prevalent in the following tropical regions of the world:
1. Northeast India: Jhum cultivation is extensively practiced in the states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura.
2. Southeast Asia: Jhum cultivation is also practiced in parts of Southeast Asia, including Thailand, Laos, and Myanmar.
3. Central America: The indigenous communities in Central America, particularly in Guatemala, Honduras, and Nicaragua, also practice jhum cultivation.
4. Africa: Jhum cultivation is practiced in some parts of Africa, including Cameroon, Congo, and Madagascar.
Conclusion
Jhum cultivation is prevalent in tropical regions of the world, where it is a vital source of livelihood for many indigenous communities. However, the practice has been criticized for its impact on the environment, including deforestation, soil erosion, and loss of biodiversity. As such, there have been efforts to promote sustainable alternatives to jhum cultivation, such as agroforestry and sustainable land management practices.

Direction: Read the case study given below and answer the questions that follow:Depending on the mode of occurrence and the nature of the ore, mining is of two types: surface and underground mining. The surface mining also known as open-cast mining is the easiest and the cheapest way of mining minerals that occur close to the surface. Overhead costs such as safety precautions and equipment are relatively low in this method. The output is both large and rapid. When the ore lies deep below the surface, underground mining method (shaft method) has to be used. In this method, vertical shafts have to be sunk, from where underground galleries radiate to reach the minerals. Minerals are extracted and transported to the surface through these passages. It requires specially designed lifts, drills, haulage vehicles, ventilation system for safety and efficient movement of people and material. This method is risky. Poisonous gases, fires, floods and caving in lead to fatal accidents. The developed economies are retreating from mining, processing and refining stages of production due to high labour costs, while the developing countries with large labour force and striving for higher standard of living are becoming more important. Several countries of Africa and few of south America and Asia have over fifty per cent of the earnings from minerals alone.Why developed economies are retreating from mining, processing and refining stages of production?- a)Time consuming

Ankit Shah answered |
Nomadic herders move from north to south in winters and from south to north in summers in the tundra region. The tundra is a vast, treeless region that is located in the northern hemisphere, mostly in the Arctic circle. The tundra is characterized by low temperatures, short growing seasons, and permafrost.
Reasons for Migration:
Herders in the tundra region move in search of food and water for their livestock. Due to the harsh conditions in the tundra, vegetation is scarce, and water is often frozen. Hence, herders need to move to areas where there is enough food and water for their livestock.
Summer Migration:
In the summer, the tundra region experiences a brief growing season when plants can grow and provide food for livestock. Herders move their livestock to these areas to graze and fatten them up for the winter.
Winter Migration:
In the winter, the tundra is covered in snow and ice, making it impossible for livestock to graze. Herders move their livestock to areas where they can find food and water. They also move to areas where their livestock can be protected from the harsh winter conditions.
Conclusion:
In conclusion, nomadic herders in the tundra region move from south to north in summers and from north to south in winters in search of food and water for their livestock. This migration is necessary for the survival of both the herders and their livestock in the harsh conditions of the tundra.

The Tundra Region of Eurasia
The second region mentioned in the question extends over the tundra region of Eurasia. Here is an explanation of what this means:
Tundra Region: The tundra is a biome characterized by low temperatures, short growing seasons, and permafrost (permanently frozen soil). This region is found in the far northern hemisphere, including parts of Alaska, Canada, Scandinavia, and Russia.
Eurasia: Eurasia is the combined landmass of Europe and Asia. It is the largest continent on Earth and is home to a wide variety of landscapes and biomes.
Extent of the Region: The question suggests that the second region extends over the tundra region of Eurasia, meaning that it includes parts of both Europe and Asia. This could refer to the entire tundra biome found in Eurasia or a specific portion of it.
Importance of the Tundra: The tundra region is an important part of the global ecosystem, as it provides habitat for many unique species of plants and animals. It also plays a key role in regulating the Earth's climate, as the permafrost stores large amounts of carbon that would otherwise be released into the atmosphere.
Conclusion: In summary, the second region mentioned in the question extends over the tundra region of Eurasia, which is an important part of the global ecosystem and plays a key role in regulating the Earth's climate.

Aravind Chawla answered |
In the tropics, shifting cultivation is commonly practiced. Shifting cultivation, also known as slash-and-burn agriculture or swidden agriculture, is a traditional method of farming that involves clearing a plot of land, cultivating it for a few years, and then abandoning it to allow the land to regenerate. This process is then repeated in a different area, creating a cycle of cultivation and fallow periods.
Explanation:
Shifting Cultivation:
- Shifting cultivation is a traditional agricultural system that has been practiced for centuries in the tropics.
- It involves clearing a small area of land by cutting down vegetation and burning it, which releases nutrients into the soil.
- The cleared land is then cultivated for a few years until the soil fertility decreases, and weeds and pests become problematic.
- After this period, the land is left fallow, allowing the vegetation to regrow and restore soil fertility.
- The process is then repeated in a different area, creating a rotational system of cultivation and fallow periods.
Advantages of Shifting Cultivation:
- Shifting cultivation allows farmers to utilize the fertile soil of the tropics without the need for expensive inputs such as fertilizers.
- It is well-suited to the tropical environment, where soils are often nutrient-poor and prone to leaching.
- The fallow periods allow the land to regenerate and restore its fertility naturally, reducing the need for external inputs.
- Shifting cultivation also provides opportunities for biodiversity conservation, as the fallow periods allow natural vegetation to recover and provide habitat for wildlife.
Challenges of Shifting Cultivation:
- However, shifting cultivation has faced criticism due to its environmental impact and perceived inefficiency.
- The practice of slash-and-burn can lead to deforestation and habitat loss if not properly managed.
- Additionally, as populations have increased and land availability has decreased, the length of fallow periods has often been shortened, leading to soil degradation and decreased agricultural productivity.
- Efforts have been made to promote alternative agricultural practices that are more sustainable and productive, such as agroforestry and terrace farming.
In conclusion, shifting cultivation is the type of cultivation commonly practiced in the tropics. It is a traditional agricultural system that involves clearing small areas of land, cultivating them for a few years, and then allowing them to regenerate naturally during fallow periods. While shifting cultivation has its advantages, it also faces challenges in terms of sustainability and productivity.
