These four cycles stated
above are all series of processes of change. The only difference is the element
included. Definitions are provided below as to how is it differentiated from the
other:
Rock cycle is a model that shows the cycle of
processes that rocks have undergone in the Earth’s crust among the three
main rock types: sedimentary, igneous and metamorphic.
Water cycle- this shows the processes by which
water circulates between the ocean, atmosphere, and land. It has three
processes mainly evaporation, condensation, and precipitation. This cycle
shows how water is being restored to be of use to Earth’s inhabitants.
Carbon cycle- this is a series of processes
wherein carbon compounds are being converted in the environment. This is mainly
involved in the incorporation of carbon dioxide being used in
photosynthesis. This is also being used to maintain the equilibrium of the
ecosystem as carbon dioxide is one of the important elements for organisms
to survive.
Nitrogen cycle- this involves series of
processes wherein nitrogen and all of its compounds are being converted
between the environment and the living organisms.
