FAQs on Minerals & Energy Resources Summary Class 10 Social Science Chapter 1
|1. What are minerals and why are they important?
Ans. Minerals are naturally occurring inorganic substances that are found in the earth's crust. They have various chemical compositions and physical properties. Minerals are important because they are the building blocks of rocks and play a crucial role in the formation of landforms. They are also essential for various industrial and economic activities, as they are used in the production of metals, fertilizers, construction materials, and energy resources.
|2. What are the different types of energy resources?
Ans. There are various types of energy resources. Some of the major ones include fossil fuels (coal, oil, and natural gas), nuclear energy, renewable energy (solar, wind, hydroelectric, geothermal, and biomass), and non-renewable energy resources (uranium, thorium). Each type of energy resource has its own advantages, disadvantages, and environmental impacts.
|3. How are minerals extracted from the earth's crust?
Ans. Minerals are extracted from the earth's crust through various mining methods. The two main types of mining techniques are surface mining and underground mining. In surface mining, minerals near the surface are extracted by removing the overlying soil and rock layers. This method is commonly used for minerals like coal and iron ore. In underground mining, tunnels are dug deep into the earth to reach the mineral deposits. This method is used for minerals that are deeper underground, such as gold and copper.
|4. What are the environmental impacts of mining minerals?
Ans. Mining minerals can have significant environmental impacts. Some of the common environmental issues associated with mining include deforestation, habitat destruction, soil erosion, water pollution, and air pollution. The extraction and processing of minerals often require the use of heavy machinery, which can result in noise pollution and the release of harmful gases. Mining activities can also disrupt local ecosystems and lead to the loss of biodiversity.
|5. How can we conserve minerals and energy resources?
Ans. Conservation of minerals and energy resources is essential for sustainable development. Some ways to conserve these resources include promoting the use of renewable energy sources, improving energy efficiency in industries, promoting recycling and reuse of materials, and implementing strict regulations on mining activities to minimize environmental impacts. Additionally, raising awareness about the importance of conservation and adopting responsible consumption practices can also contribute to the preservation of minerals and energy resources for future generations.
