Water vapor can also be indirect evidence supporting the presence of extraterrestrial liquid water in the case of some planetary mass objects. Water vapor, which reacts to temperature changes, is referred to as a 'feedback', because it amplifies the effect of forces that initially cause the warming. Therefore, it is a greenhouse gas. [2]
Condensation: The transformation of water vapor to liquid water droplets in the air, creating clouds and fog. [8] Evaporation: The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. [9] The source of energy for evaporation is primarily solar radiation.
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
This is an accepted version of this page This is the latest accepted revision, reviewed on 28 February 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
The soil-plant-atmosphere continuum (SPAC) is the pathway for water moving from soil through plants to the atmosphere. Continuum in the description highlights the continuous nature of water connection through the pathway. The low water potential of the atmosphere, and relatively higher (i.e. less negative) water potential inside leaves, leads ...
View of Amazon basin forest north of Manaus, Brazil. The term “biotic pump” infers a circulation system driven by biological processes. This concept shows forests as being the major factors in manipulating atmospheric processes to cycle rainfall taken up by trees throughout all continents and back to the atmosphere for further cycling.

The planet, named GJ 9827d, is about twice Earth’s diameter, and it’s the smallest exoplanet found to have water vapor in its atmosphere, according to a new study. Water is essential for life ...
Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the atmosphere. [ 2 ] : 2908 It covers both water evaporation (movement of water to the air directly from soil, canopies , and water bodies) and transpiration (evaporation that occurs ...
