  2. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.

  3. Runoff (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Runoff_(hydrology)

    The water cycle (or hydrologic cycle or hydrological cycle) is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and ...

    en.wikipedia.org/wiki/Hydrology

    Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) 'water' and -λογία () 'study of') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and ...

  6. Deep water cycle - Wikipedia

    en.wikipedia.org/wiki/Deep_water_cycle

    Water carried into the mantle eventually returns to the surface in eruptions at mid-ocean ridges and hotspots. [8] This circulation of water into the mantle and back is known as the deep water cycle or the geologic water cycle. [9] [10] [11] [5] Estimates of the amount of water in the mantle range from 1 ⁄ 4 to 4 times the water in the ocean ...

  7. Stream - Wikipedia

    en.wikipedia.org/wiki/Stream

    Most of this water re-enters the atmosphere either by evaporation from soil and water bodies, or by plant evapotranspiration. By infiltration some of the water sinks into the earth and becomes groundwater, much of which eventually enters streams. Most precipitated water is partially bottled up by evaporation or freezing in snow fields and glaciers.

  8. Lake - Wikipedia

    en.wikipedia.org/wiki/Lake

    Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water.
