Minerals and Energy Resources

Case Study 1: Importance of Minerals in Economic Development

Context:
Minerals are vital for the industrial development of any nation. India is rich in mineral resources, which include ferrous and non-ferrous minerals like iron ore, manganese, copper, and bauxite.

    • A. Enhancing tourism
    • B. Supporting industrial growth and infrastructure
    • C. Reducing population growth
    • D. Promoting agriculture
  2. Which of the following is a ferrous mineral found in India?
    • A. Gold
    • B. Copper
    • C. Iron ore
    • D. Limestone
  3. What is a major challenge related to mining activities?
    • A. Increase in urban population
    • B. Ecological degradation and displacement of communities
    • C. Expansion of agriculture
    • D. Enhanced biodiversity
  4. How can minerals be managed sustainably?
    • A. Over-extracting them
    • B. Encouraging wastage
    • C. Implementing policies to balance extraction with environmental care
    • D. Disregarding environmental concerns

Case Study 2: Non-Renewable Energy Resources and Their Impact

Context:
Non-renewable energy resources such as coal, petroleum, and natural gas have played a crucial role in driving industrialization and modern transportation systems across the world. India, with its vast reserves of coal, is heavily dependent on these energy resources. While they provide the bulk of the country’s energy needs, their over-reliance poses challenges. These resources are finite and will eventually be exhausted. Additionally, their extraction and use contribute significantly to environmental issues like air pollution and greenhouse gas emissions, which accelerate global warming and climate change.

Questions:

  1. What is a key characteristic of non-renewable energy resources?
    • A. They are infinite in supply
    • B. They can be replenished quickly
    • C. They are limited and will deplete over time
    • D. They have no impact on the environment
  2. Which of the following is a non-renewable energy resource?
    • A. Wind energy
    • B. Coal
    • C. Solar power
    • D. Hydroelectric power
  3. What is a major environmental consequence of using non-renewable energy resources?
    • A. Reduction in air pollution
    • B. Increase in global warming and climate change
    • C. Decrease in energy demand
    • D. Improved biodiversity
  4. Why is over-reliance on non-renewable energy resources problematic?
    • A. Because they promote sustainable development
    • B. Because they can be easily replaced
    • C. Because they are limited and contribute to environmental degradation
    • D. Because they are always available

Case Study 3: Renewable Energy and Sustainability

Context:
With the growing concerns over the depletion of non-renewable energy resources and environmental sustainability, there is a global shift towards renewable energy sources. India has immense potential in renewable energy, particularly in solar, wind, and hydropower. These resources are inexhaustible and can be replenished naturally. The government is investing in solar power projects and wind farms to reduce dependency on coal and oil. However, despite the significant potential, the adoption of renewable energy in India is slower than expected due to high initial costs, inadequate infrastructure, and the need for technological advancement.

Questions:

  1. What is a key advantage of renewable energy sources?
    • A. They are limited
    • B. They cannot be replenished
    • C. They are inexhaustible and environmentally friendly
    • D. They cause significant pollution
  2. Which of the following is a renewable energy source?
    • A. Coal
    • B. Solar energy
    • C. Natural gas
    • D. Petroleum
  3. What is a major barrier to the adoption of renewable energy in India?
    • A. Low initial costs
    • B. Inadequate infrastructure and high setup costs
    • C. Unlimited supply of fossil fuels
    • D. Excessive government subsidies
  4. Which renewable energy resource is India investing in heavily to reduce coal dependency?
    • A. Petroleum
    • B. Wind and solar energy
    • C. Natural gas
    • D. Nuclear power

Case Study 4: Role of Minerals in Everyday Life

Context:
Minerals are used in everyday life in ways we may not always recognize. From the iron used in construction to the copper wiring in electronics, minerals form an essential part of the goods and services we rely on. India is one of the leading producers of iron ore, bauxite, and mica, which are crucial in manufacturing industries. However, the over-extraction of minerals can lead to depletion, making it critical for industries to use them efficiently. Recycling and conservation strategies are important in ensuring minerals are available for future generations.
