How are flood plains formed?
Answers
Answer:
During floods, layers of fine soil and other material called sediments are deposited on the river bank. This leads to the formation of a flat fertile flood plains.
Step-by-step explanation:
Floodplains are formed in two ways: by erosion; and by aggression. Erosional floodplain is created as a stream cuts deeper into its channel and laterally into its banks. A floodplain, or flood plain, is flat or nearly flat land adjacent to a stream or river that experiences occasional flooding.
Flood plains are made by a meander eroding sideways as it travels downstream. When a river breaks its banks and floods, it leaves behind layers of alluvium (silt). These gradually build up to create the floor of the flood plain.
