Question

Write the formation flood plains

Answer 1

Answer:

Explanation:

A floodplain or flood plain is an area of land adjacent to a stream or river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge

 Floodplains are formed when a meander erodes sideways as it travels downstream. When a riverbreaks its banks, it leaves behind layers of alluvium (silt). These gradually build up to create the floor of the plain.
