By contrast those developing the biotic pump concept state that “forest and trees are prime regulators within the water, energy and carbon cycles.” [6] In areas were there is more rain is currently being evaporated (on land versus over the ocean), the atmospheric volume decreases at a much quicker rater. This causes low pressure to form ...
Consequentially, the air over the water's surface is heated and this leads to showers developing. Furthermore, rain showers generally develop over a waterbody in autumn to early winter due to the higher water temperature compared to the air above. [7] Only when the lake water is cooler than the air temperature, cloud development is hindered ...
As these larger water droplets descend, coalescence continues, so that drops become heavy enough to overcome air resistance and fall as rain. [30] Raindrops have sizes ranging from 5.1 to 20 millimetres (0.20 to 0.79 in) mean diameter, above which they tend to break up. Smaller drops are called cloud droplets, and their shape is spherical.
Water returns to the land surface at lower elevation than where it infiltrated, under the force of gravity or gravity induced pressures. Groundwater tends to move slowly and is replenished slowly, so it can remain in aquifers for thousands of years. Transpiration: The release of water vapor from plants and soil into the air.
Transpiration is the movement of water through a plant and out of its leaves and other aerial parts into the atmosphere. This movement is driven by solar energy. [4] In the tallest trees, such as Sequoia sempervirens, the water rises well over 100 metres from root-tip to canopy leaves. Such trees also exploit evaporation to keep the surface cool.
This gradient of water potential causes endosmosis. The endosmosis of water continues until the water potential both in the root and soil becomes equal. It is the absorption of minerals that utilise metabolic energy, but not water absorption. Hence, the absorption of water is indirectly an active process in a plant's life.

Some rain collecting on an acer leaf. Interception [ 1 ] refers to precipitation that does not reach the soil, but is instead intercepted by the leaves, branches of plants and the forest floor. It occurs in the canopy (i.e. canopy interception ), and in the forest floor or litter layer (i.e. forest floor interception [ 2 ] ).
