Short and easy definition of water cycle, nitrogen cycle, carbon cycle, and phosphorus cycle.

Water cycle-the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land

Nitrogen cycle-the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition

Carbon cycle - the series of processes by which carbon compounds are interconverted in the environment

Phosphorus cycle - The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

I actually dont have the time right now but if you look up definition of (word) the definition will come up. Just put it into a shorter version!
