When To Use
Evapotranspiration is the process of moisture moving from the earth to the atmosphere through water evaporation and plant transpiration. Evapotranspiration refers to the moving of water and moisture from the soil and plants to the atmosphere. Evaporation is water in the soil surface becoming vapor as the result of temperature and other factors. The hotter it is, for example, the more water that will evaporate.Transpiration is a plant releasing water as vapor through its leaves. Transpiration helps a plant regulate its internal temperature. Corn, a crop grown in much of the Midwestern United States, is well known for transpiring to regulate its internal temperature, for example.Because water moves to the atmosphere from a wide variety of sources, the term evapotranspiration is sometimes used broadly to describe any evaporation or movement of water from the earth to the atmosphere, even from sources other than plants and soil. Example: Evapotranspiration is a vital part of all major rainforest ecosystems.
