Briefly summarize the steps of the six natural cycles of earth. 1. rock cycle: 2. tectonic cycle: 3. water cycle: 4. carbon cycle: 5. nitrogen cycle: 6. phosphorus cycle:

Nutrient cycles are systems by which substances (chemical elements or molecules) move through the biotic (living) compartment of the earth-or the biosphere - as well as the three abiotic (non-living) compartments of the earth: the lithosphere (crust and upper mantle of the earth), the atmosphere (the gasses surrounding the earth), and hydrosphere (the water of the earth). Through this biogeochemical cycling, nutrients such as oxygen, carbon, nitrogen, phosphorous, and sulfur are used and recycled. Each of these cycles is complex. These brief descriptions and diagrams will provide a general overview of how these systems work and why they are important.
