Question

With reference to river as an agent of gradation, consider the following statements:

As a river overflows its banks during a flood, it drops much of its coarser-grained load immediately, forming landforms called natural levees.

Particles that roll and slide along the river bottom are called bed load.

At a bend in a river, deposition occurs on the outside of the bend and erosion occurs on the inside of the bend.

Which of the statements given above is/are correct?

Options:

A . 1, 2 and 3

B . 1 only

C . None

D . 1 and 2

Answer: Option D
Answer: (d)
Generally, the river deposits coarse sediments on its banks. This deposition takes place every year. It raises the level of banks and takes the shape of natural embankments. Deposition of sediments also takes place in the channel of the river.
It raises the bed of the river. It is on account of this reason that during floods the river again cuts through its banks and spreads out and floods the surrounding areas.
