Question

why flood plains are very fertile​

Answer 1

Answer:

floodplains are usually very fertile agricultural areas. Floods carry nutrient-rich silt and sediment, and distribute it across a wide area. floodplains are flat and often have relatively few boulders or other large obstacles that may prevent farming.

Answer 2

Answer:

Flood plains are fertile because of the nutrients they wash onto land. The soil in riverbeds is very fertile, so it helps fertilize the ground. Also, flood plains are near a river, so there is moisture.
