Question

Describe three main characteristics of a delta

Answer 1

(1) shape: like the Greek word ‘delta’(∆)

Answer 2

Answer:

1. Deltas are wetlands that form when rivers flow into another body of    water, such as an ocean, lake, or another river.
2. A delta includes a distributary network—a series of smaller, shallower channels, called distributaries, that branch off from the main river. In a delta, heavier, coarser material settles first. Smaller, finer sediment is carried farther downstream.
3. A delta is sometimes divided into two parts: Subaqueous and Subaerial. The subaqueous part of a delta is underwater.
