Answer 2

➭ AnSwer :-

⟹ Dam :-

• Dam, structure built across a stream, a river, or an estuary to retain water.
• Many dams are built for more than one purpose; for example, water in a single reservoir can be used for fishing, to generate hydroelectric power, and to support an irrigation system.

⟹ Uses of dams :-

• A dam is usually constructed across a river to create a reservoir in the valley behind by storing the water that flows into it naturally.
• Sometimes, they are built across dry valleys, or valleys with small streams, to create a storage area for water that is transported from elsewhere.
