What is the name of the stream that flows through the deposits of the delta at the mouth of the river?
A. Canal
B. Delta-mouth
C.Lake
D Distributary

Answer 1

Hint: The mouth of the river refers to the place where the river joins the large lake or ocean.This area of the river is a place for much activities.Gravel, silt and clay are deposited at the mouth of the river.

Complete answer: When the mouth of the river has large deposits of alluvium, a delta is created.Therefore the name of the stream that flows through the deposits of the delta at the mouth of the river is called a distributary. A distributary is referred to as the part of the stream that separates itself from the main stream channel. Distributaries are a common feature in the river deltas.Distributaries are opposite of tributaries.
Looking at the options:
Option A: A canal is an artificial navigation of water from a large water body. Therefore this is incorrect.
Option B: Delta mouth is the area where the mouth of the river is extended into the body of water in which it empties itself. Therefore this is incorrect.
Option C: Lake is a large body of water which is surrounded by land. This too is incorrect.
Option D: Distributary is the stream of water that separates itself from the main water channel. Hence this is the correct answer.

Therefore, Option D is the right answer.

Note: The river delta is very significant ecologically because it carries a large number of species who assemble together depending on the position of the landscape.The river delta got its name from the delta of river Nile which is shaped like the Greek letter ‘delta’.
