Question
Explain briefly about evaporation.
✓
Answer
The action of water evaporating from the heat of the sun is called evaporation.
As the temperature rises.
As the action of evaporation accelerates, the air mixes with moisture as long as it has the capacity to absorb moisture, thus, the action of evaporation continues until the air is saturated, the intensity of evaporation depends mainly on temperature, air dryness and wind speed.
Hot and dry air has a higher capacity to absorb moisture.
As a result it increases the intensity of evaporation.
The wind blows through the upper surface of the reservoirs, carrying moisture with it.
Thus, the wind increases the intensity of evaporation.
Evaporation occurs in the summer season than in the winter.
While there is very little evaporation at the pole regions.
