What is evapotranspiration?

Evapotranspiration is a combination of evaporation and transpiration. Evaporation is a physical process that transforms liquid water into vapor by absorbing heat. Transpiration is the biological process of plants releasing water vapor through leaves. This water was previously pulled up
