Water will evaporate from any wetted surface. A
.significantly large fraction of the rainfall that falls on land is returned to
the atmosphere in this fashion. In addition water is assimilated by root systems
of growing plants and is later transpired from the leaf surfaces by a process
essentially identical to evaporation. The two effects, evaporation and
transpiration, cannot be individually discriminated for their effectiveness in
returning rainfall to the atmosphere, but their sum contribution can be
evaluated and is usually called the evapotranspiration factor. The fraction of
rain falling on the United States that is returned to the atmosphere by
evapotranspiration, for example, is 70 percent; for the world as a whole,
approximately 62 percent. In arid countries such as Australia the fraction is
larger, and in less arid areas such as the United Kingdom i A. Water evaporated to atmosphere is unavailable to man because it is from useless plants. B.
