Question

)Explain any two processes through which water enters into atmosphere

Answer 1

Answer:

Water enters the atmosphere through evaporation, transpiration, excretion and sublimation. Transpiration: It is the loss of water from plants (via their leaves). Evaporation: It is the process by which water changes from a liquid to a gas or vapour.

Answer 2

Answer:

Water enters the atmosphere through evaporation and transpiration.

Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor.

The process of liquid changing into vapours even below its boiling point is called as evaporation. Some particles in a liquid always have more kinetic energy than the others. Thus, the fast moving particles of a liquid are constantly escaping from the liquid to form vapour
