(Class 10 SSt Sample Question Paper)

Answer 1

SOLUTION:
Differences between hydroelectricity and thermal electricity are as follows:

HYDROELECTRICITY:
1.Hydro electricity is generated by the force of running water falling on turbines.

2. It does not cause any atmospheric pollution.

3. Hydroelectricity is an unlimited resource i.e water is perennial or inexhaustible.

4. It is cheaper in the long run.


THERMAL ELECTRICITY:
1.Thermal electricity is generated by coal or Petroleum.

2. It causes atmospheric pollution.

3. It is a limited resource. Its sources are exhaustible or nonrenewable like coal and petroleum.

4. It is expensive in the long run.

Answer 2

Difference between Thermal Power and Hydroelectric Power are:

Thermal Power

(i) It is generated from petroleum (oil) or coal.

(ii) Its sources (coal and oil) are exhaustible.

(iii) On burning coal and oil they cause a lot of pollution.

(iv) It is expensive in the long run.

Hydroelectric Power

(i) It generated from water falling on turbines.

(ii) Its source is perennial, i.e., in­exhaustible.

(iii) It causes no pollution.

(iv) It is cheaper in the long run.
