Question

Why is deltaic alluvium more fertile than coastal alluvium?

Give a geographical reason for the following:

Deltaic alluvium is more fertile than the coastal alluvium.

Answer 1

Deltaic alluvium (Khadar) is more fertile than coastal alluvium (Bhangar) as new layers are deposited year after year during monsoonal floods.

Answer 2

Coastal alluvium is less effective at conserving water than deltaic alluvium due to its combination with sand. The deltaic alluvium contains newly deposited alluvial components.
