which process is responsible for formation of alluvial plain
Answers
An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms.
Answer:
Explanation:
* An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms.
* It consists of silt, sand, clay, and gravel, as well as much organic matter. Alluvial deposits are usually most extensive in the lower part of a river's course, forming floodplains and deltas, but they may form at any point where the river overflows its banks or where the flow of a river is checked.
* Steep channels and other sediment sources feed out onto flat planes. The energy of the system drop dramatically, leading to the deposition of more coarse-grained sediments. ... They are formed where neighbouring alluvial fans feed into a closed-system valley.
