Question

Describe three processes by which water moves into the atmosphere. Which process accounts for most of the water moving into the atmosphere?

Answer 1

Answer: The three processes are;

1) Transpiration

2) Evaporation

3) Sublimation

Evaporation accounts for most of the water moving into the atmosphere

Explanation:

Water is absorbed into the atmosphere by transpiration, evaporation and sublimation.

Transpiration: This refers to the loss of water in form of water vapor from plants via their leaves. Only a little amount of water absorbed by plants is used for their nourishment. The remaining is removed from the aerial part of the plants either through the stomata, lenticels or the cuticle.

Sublimation: This method of water supply to the atmosphere is through the transformation of ice or snow into water vapor.

Evaporation: This process accounts for most of the water moving into the atmosphere. It is the process through with water from seas, oceans, lakes, rivers changes to gas. This method provides nearly 90% of water in the atmosphere.
