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

1. What are the main types of minerals, and how are they classified?
Ans.Minerals are primarily classified into two categories: metallic and non-metallic minerals. Metallic minerals, such as iron ore, copper, and bauxite, are known for their luster and conductivity. Non-metallic minerals include resources like limestone, gypsum, and coal, which do not have metallic properties. Additionally, minerals can be further categorized based on their origin, such as igneous, sedimentary, and metamorphic minerals.
2. How do energy resources differ from mineral resources?
Ans.Energy resources primarily refer to sources that can be used to generate energy, such as coal, oil, natural gas, and renewable resources like solar and wind energy. In contrast, mineral resources are naturally occurring substances that are extracted for various uses, including construction, manufacturing, and technology. While both categories are essential for economic development, energy resources are specifically focused on energy production and consumption.
3. What are some examples of renewable energy resources, and why are they important?
Ans.Renewable energy resources include solar energy, wind energy, hydroelectric power, geothermal energy, and biomass. These resources are important because they are sustainable and can be replenished naturally over time. They contribute to reducing greenhouse gas emissions and dependence on fossil fuels, making them vital for combating climate change and promoting environmental sustainability.
4. What impact does mining have on the environment?
Ans.Mining can have several negative impacts on the environment, including deforestation, soil erosion, and water pollution. The extraction process can disturb the natural habitat, leading to biodiversity loss. Additionally, the waste produced during mining operations can contaminate local water sources, affecting both ecosystems and human health. Implementing proper regulations and sustainable practices is essential to mitigate these effects.
5. Why is it important to conserve mineral and energy resources?
Ans.Conserving mineral and energy resources is crucial for several reasons. First, these resources are finite and can become depleted with excessive use. Sustainable management ensures that future generations have access to essential materials and energy. Additionally, conservation helps reduce environmental degradation associated with extraction and consumption, promoting a healthier planet. Efficient use and recycling of these resources can lead to economic benefits and energy security.
