✓

Answer

  1. The rate of evaporation in a coastal area is less because of high humidity

Explanation:

The rate of evaporation in a coastal area is less because of high humidity.

High humidity represents higher concentration of water vapour in the air due to which temperature of the surrounding atmosphere decreases and the rate of evaporation also decreases.
