liquid state to its gas state by random particle
movement. Evaporation usually occurs at the
surface of a liquid over a wide range of
temperatures.

turnover
An increase in nutrients in a lake or pond.
Eutrophication can occur naturally or as a result
of pollution, and causes increased growth of
algae and plants.
