Evaporation of water from vegetation into the atmosphere is known as transpiration (B) or evapotranspiration.
Infiltration (A) is the downward penetration of water into a substance such as soil.
Precipitation (C) is the falling products of condensation from the atmosphere such as rain, snow, or hail.
Condensation (D) is the process of water going from a gas (i.e. vapour) to a liquid.
