1) Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Solar radiation is the source of energy for evaporation.
2) Condensation is phase change process in which the water changes from a gas to a liquid, the vapor becomes a cloud.
3) Precipitation is falling of the condensed water vapor as rain, snow, fog drip.
The water cycle (hydrological cycle) is the continuous movement of water all around the Earth.
The water moves from one reservoir to another, such as river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow.
