What do you mean by Water Cycle?

The water cycle—technically called as the hydrologic cycle—is the flow of water within the earth's hydrosphere, that involving changes in the physical state of water between the liquid, solid, and gas phases. The hydrologic cycle refers to the continuous exchange of water that connecting the atmosphere, land, surface and subsurface waters, and organisms. Additionally to storage in different compartments (the ocean is one such "compartment"), the multiple cycles that make up the earth's water cycle have five main physical actions. They are the evaporation, precipitation, infiltration, runoff, and subsurface flow.
