  2. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...

  3. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The processes that drive these movements are evaporation, transpiration, condensation, precipitation, sublimation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2]

  4. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Evaporation: the movement of water directly to the air from sources such as the soil and water bodies. It can be affected by factors including heat, humidity, solar radiation and wind speed. [6]: Ch. 1, "Evaporation" Transpiration: the movement of water from root systems, through a plant, and exit into the air as water vapor.

  5. Vaporization - Wikipedia

    en.wikipedia.org/wiki/Vaporization

    Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs on the surface. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure ...

  6. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Water vapor, water vapour or aqueous vapor is the gaseous phase of water.It is one state of water within the hydrosphere.Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice.

  7. Hydrology - Wikipedia

    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 ...

  8. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    The microscopic process of evaporation and condensation at the liquid surface. If vapor pressure exceeds the thermodynamic equilibrium value, condensation occurs in presence of nucleation sites. This principle is indigenous in cloud chambers, where ionized particles form condensation tracks when passing through. The pistol test tube experiment.

  9. Transpiration - Wikipedia

    en.wikipedia.org/wiki/Transpiration

    Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. It is a passive process that requires no energy expense by the plant. [ 1 ]
