(b) Exhaustible sources are those sources of energy, which will deplete and exhaust after a few hundred years. Coal, petroleum, etc. are the exhaustible sources of energy. Inexhaustible resources of energy are those sources, which will not exhaust in future. These are unlimited. Bio-mass is one of tRead more
(b) Exhaustible sources are those sources of energy, which will deplete and exhaust after a few hundred years. Coal, petroleum, etc. are the exhaustible sources of energy. Inexhaustible resources of energy are those sources, which will not exhaust in future. These are unlimited. Bio-mass is one of the inexhaustible sources of energy. Yes. The options given in (a) and (b) are the same.
(a) The source of energy that replenishes in nature is known as renewable source of energy. Sun, wind, moving water, bio-mass, etc. are some of the examples of renewable sources of energy. The source of energy that does not replenish in nature is known as non-renewable source of energy. Coal, petrolRead more

The source of energy that does not replenish in nature is known as non-renewable source of energy. Coal, petroleum, natural gas, etc. are some of the examples of non – renewable sources of energy.
(c) Very high tides are required in order to extract energy from tides. Tidal energy is harnessed by constructing a dam across a narrow opening to the sea. The locations where such dams can be built are limited. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-1Read more

(b) Very strong ocean waves are required in order to extract energy from waves.
(a) Wind energy is harnessed by windmills. One of the limitations of extracting energy from wind is that a windmill requires wind of speed more than 15 km/h to generate electricity. Also, a large number of windmills are required, which covers a huge area. For a 1 MW generator, the farm needs about 2Read more

Also, a large number of windmills are required, which covers a huge area. For a 1 MW generator, the farm needs about 2 hectares of land. The initial cost of establishment of the farm is quite high. Moreover, since the tower and blades are exposed to the vagaries of nature like rain, Sun, storm and cyclone, they need a high level of maintenance.
