GEOLOGY

Detailed explanation-1: -Precipitation, evaporation, freezing and melting and condensation are all part of the hydrological cycle-a never-ending global process of water circulation from clouds to land, to the ocean, and back to the clouds.

Detailed explanation-2: -The water cycle is a way that water moves all around the Earth. It never stops, it does not have a beginning or an end.

Detailed explanation-3: -A fundamental characteristic of the hydrologic cycle is that it has no beginning an it has no end. It can be studied by starting at any of the following processes: evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage.

Detailed explanation-4: -The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Detailed explanation-5: -As has already been pointed out, the Sun provides the excess energy for the water cycle to continue indefinitely (or at least for as long as we have the Sun).
