Question

Which of the following is formed at the mouth of a river as sediment is carried to the ocean?

A.
a lake
B.
an island
C.
a delta
D.
a bay

Answer 1

C. a delta. Because a delta is the only one of those choices to where it is formed at the mouth of a river

Answer 2

Option (C)

Step-by-step explanation:

A river flows from a region of higher elevation to a region of lower elevation and is structurally controlled. As it flows towards the sea or ocean body, the strength of the river decreases and carries a lesser amount of sediments along with it. These sediments are sometimes deposited in a large amount in such a way that the sea waves cannot erode, thereby resulting in the formation of layers of sediments, which are commonly known as delta. A delta is considered to be the mouth of the river.

Hence, the correct answer is option (C).
