vampirchik [111]

Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:

Transpiration is the loss of water from plants (via their leaves).

Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).

Animals excrete water by respiration and by passing urine.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
