Tributary
- A river or a stream that merges with the main river by discharging its all water is known as a tributary.
Delta
- The river near its mouth forms a very low-lying and almost no slope wetting area, through depositing its sediments known as a delta.
- The delta formed by the Ganga and Brahmaputra rivers along the Bay of Bengal is the world's largest delta.
Polyps -&- Corals
- The very small /tiny Marine animals are called polyps.
- Corals are the skeleton of these polyps.
- The joining process of these Skelton along with the sedimentation resulted in the formation of coral Iceland.
- An island is a feature which is surrounded from all its a corner by a water body.
Slope of India
- The slope of India is from west to east that's why the majority of the river naturally flows toward the East and merges into the Bay of Bengal.
