    Hello!

    I am an environmental engineering student, and doing my master degree. I am studying environmental chemsitry as one subject in this semester. We have discussed about the cycles of the elements in nature and come out with some idea for the characteristics of these cycles. Here is a few principles which we have found out in our group discussion:
    1)every cycle has biological and chemical portion.
    2)every cycle have aerobic and anaerobic portions.
    3)every cycle has precursor(storage) with valence of zero and it can be oxizided or reduced.
    4)Every cycle can feature oxidation and reduction process.
    5)Every cycle has conservation of matter and charges.
    6)In every cycle, there will be gaesours(air), liquid(water), and solid(water).
    7)The complexicity of each cycle is different according to their variety of elemental valence.
    8)Every cycle have organic and inorganic components.
    9)Every cycle is made of both natural and anthropogenic parts.
    10)Every cycle is driven by energy which can be geochemical or biochemical (photosynthesis, and chemosynthesis).

    It would be grateful if anyone could comment or correct these above principles (what we call). And I am also wondering if any new principle which we are missing in our discussion could be suggested.

    Looking forward to your reply, comments or suggestions!

    According to our today discussion, we have found out another principle: every cycle has biogeochemical reaction, which takes place in biosphere, atmosphere, hydrosphere, and lithosphere. Our discussion is becoming harder and tough. Please help us to find new principles. looking forwards to you all.
