FAQs on Minerals and Energy Resources Video Lecture - Social Studies (SST) Class 10

1. What are the primary types of minerals and their classifications?
Ans. Minerals are naturally occurring, inorganic substances with a definite chemical composition and crystal structure. They are primarily classified into two categories: metallic and non-metallic minerals. Metallic minerals include ores of metals like iron (Fe), copper (Cu), and aluminum (Al), which are used in various industries. Non-metallic minerals include resources like limestone, gypsum, and mica, which are used in construction, agriculture, and manufacturing.
2. How are energy resources categorized, and what are some examples?
Ans. Energy resources are typically categorized into two main types: renewable and non-renewable resources. Renewable resources are those that can be replenished naturally, such as solar energy, wind energy, and hydropower. Non-renewable resources, on the other hand, are finite and include fossil fuels like coal, oil, and natural gas, as well as nuclear energy from uranium. Each type plays a crucial role in meeting the energy demands of society.
3. What is the significance of mineral resources for a country’s economy?
Ans. Mineral resources are vital for a country's economy as they contribute significantly to industrial development and job creation. They are essential for manufacturing processes, construction, and the production of energy. The extraction and export of minerals can generate substantial revenue and support the development of infrastructure, thereby enhancing overall economic growth and stability.
4. What are some environmental impacts associated with mining activities?
Ans. Mining activities can have several adverse environmental impacts, including deforestation, soil erosion, and water pollution. The extraction process may disrupt local ecosystems and habitats, leading to biodiversity loss. Additionally, the use of chemicals in mining can contaminate nearby water bodies, affecting both aquatic life and local communities. Sustainable mining practices are essential to mitigate these impacts.
5. How does the conservation of energy resources contribute to sustainable development?
Ans. The conservation of energy resources is crucial for sustainable development as it ensures that future generations have access to essential energy supplies. By promoting energy efficiency and the use of renewable resources, societies can reduce their reliance on non-renewable sources, decrease greenhouse gas emissions, and minimize environmental degradation. Sustainable energy practices support economic growth while protecting natural resources and promoting social equity.
