Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies.
A portion of the solar energy absorbed at the surface is used to evaporate water, either from oceans and lakes or by means of the release of water vapor via vegetation photosynthesis (a process known as transpiration or evapotranspiration, discussed more in later chapters).
