FAQs on Mnemonics: Minerals and Energy Resources - Social Studies (SST) Class 10

1. What are the major types of minerals, and how are they classified?
Ans. Minerals are generally classified into two major categories: metallic minerals and non-metallic minerals. Metallic minerals include valuable metals such as iron, copper, and aluminum, which are extracted for industrial use. Non-metallic minerals consist of materials like coal, limestone, and clay, which are used in various construction and manufacturing processes. Additionally, minerals can be categorized based on their origin, such as igneous, sedimentary, and metamorphic minerals.
2. How do renewable energy resources differ from non-renewable energy resources?
Ans. Renewable energy resources, such as solar, wind, hydro, and biomass, are derived from natural processes that replenish themselves over time. These resources are considered sustainable and have a minimal environmental impact. In contrast, non-renewable energy resources, like coal, oil, and natural gas, are finite and will deplete over time as they are consumed. The extraction and use of non-renewable resources often lead to environmental degradation and pollution.
3. What is the significance of conserving mineral resources?
Ans. Conserving mineral resources is crucial for sustainable development and environmental protection. As mineral resources are finite, their over-exploitation can lead to depletion, increased costs, and ecological imbalance. Conservation practices, such as recycling and efficient usage, help extend the life of these resources, reduce waste, and minimize the environmental impact of mining activities. This is essential for future generations and maintaining biodiversity.
4. What are some common methods of extracting minerals?
Ans. Common methods of mineral extraction include surface mining, underground mining, and placer mining. Surface mining involves removing the overburden to access minerals near the Earth's surface, while underground mining is used for deep deposits where minerals are extracted from tunnels. Placer mining involves extracting minerals from riverbeds and beaches, often used for precious metals like gold. Each method has its own environmental impacts and costs associated with it.
5. How does the use of minerals and energy resources impact the economy?
Ans. The extraction and utilization of minerals and energy resources play a vital role in economic development. They provide essential raw materials for various industries, create jobs, and contribute to national income through exports. However, reliance on these resources can also lead to economic vulnerabilities, especially in regions that depend heavily on a single resource. Therefore, diversification and sustainable practices are important for long-term economic stability.
