Answer:
The correct answer would be hydrologic cycle (hydro means "related to water").
Hydrologic cycle or water cycle refers to the cyclic movement of water in an ecosystem.
The physical processes involved in the cycling of water throughout the ecosystem are: evaporation, condensation, sublimation, precipitation, infiltration, and runoff (surface and sub-surface).
Water evaporates from the surface of the earth into the atmosphere where they condense to form clouds. When temperature decreases, the water droplets merge with each other to form bigger droplets which are precipitated in the form of rain.
Water can also precipitate in the form of snow, fog, hail sleet et cetera.
Water fall on the earth surface either infiltrate to form ground water or runoff the surface to from lakes, rivers et cetera.
