FAQs on NCERT Solutions for Class 8 Social Chapter 3 - Mineral And Power Resources

1. What are the different ways of saving energy and their resources at home?

  • We can use solar panels to store energy-absorbing from sunlight and use that for various equipment.

  • Electricity is a major part of our life. Along with using it many people waste it by putting all the electric equipment on without any reason. One should switch it off when not in use.

2. Before building huge dams one should look carefully for environmental aspects. Give reason.

Dams for human use impact the environment in a variety of ways. A large area is necessary to build the dam, and as a result, many trees in that region are chopped down.
