Delta is formed under different conditions. Outline three conditions necessary for its formation.

Answer / Solution

Delta is a low-lying swampy plain formed as a result of accumulation of deposits at the mouth of the river valley.

The following are three conditions necessary for delta formation:

1. There should be active erosion in the upper course and middle course so that the river can have a large load of deposition materials.
2. The velocity of the river in the mouth must be low to allow deposition, for this to happen the there should be a gently sloping land along the cost.
3. The load should be deposited faster than its removal by the acion of tides, waves and currents.
