Question

Give a reason for the following:

Alluvial plains are regarded as the granaries of the world.

Answer 1

Alluvial plains are regarded as the granaries of the world because they are formed by the deposition of rich, fertile soil (alluvium) by rivers. This soil is highly nutrient-rich and supports the growth of a wide variety of crops, making these plains ideal for agriculture. The Indo-Gangetic plains in India and the Mississippi River plains in the USA are examples of alluvial plains that are known for their high agricultural productivity.
