Damming rivers is useful for Producing Electricity
Explanation:
- Damming of rivers involves constructing dams on rivers and store the excess of water and in turn prevent the floods.
- Damming of rivers find another extensive use. i.e. the production of Hydroelectricity.
- Water reserved in Dams have a great Potential energy due to a great mass and height.
- When allowed to fall from such height the potential energy converts into kinetic energy.
- This kinetic energy rotates the turbine and thus its mechanical energy is converted into electrical energy.
