Final answer:
The earth's water cycle is referred to as the hydrological cycle. It involves the continuous movement of water in different forms between various reservoirs on, above, and below the Earth's surface.
Step-by-step explanation:
The earth's water cycle is referred to as the hydrological cycle. It is a biogeochemical cycle through which water is recycled on, above, and below Earth's surface. The water cycle involves processes such as evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow, and it includes the continuous movement of water in different forms (liquid, solid, and gas) between various reservoirs like oceans, atmosphere, rivers, and groundwater.
