Question

why is the Great plain fertile?​

Answer 1

Answer:

Flood plains are fertile due to the depositional activity of rivers. Rivers carry along with them eroded material like fine soil and sediments. When it overflows its banks, it deposits the eroded material and causes flood plainsto be formed. The deposited material makes the land fertile.

The grasslands in the Great Plains are associated with high productivity due to the generally reliable summer precipitation, a long growing season, and deep, fertile soils. Lands that were formally grasslands, now farmed are some of the most fertile cropland in the U.S. and the world.
