Final answer:
The hydrologic cycle details the endless movement and transformation of water across the planet, including its various states and processes like evaporation, condensation, and precipitation.
Step-by-step explanation:
The hydrologic cycle, also known as the water cycle, describes the continuous movement of water on, above, and below the surface of the Earth. This cycle includes water transitioning through various states: liquid, vapor, and ice. During the hydrologic cycle, water transfers between different reservoirs including the oceans, atmosphere, glaciers, groundwater, rivers, and the biosphere. This cycle is propelled by solar energy and gravity, which facilitate essential processes such as evaporation, condensation, precipitation, infiltration, surface runoff, subsurface flow, and transpiration.
