Is rock cycle also known as the phosphorus cycle? They are the same thing I'm guessing.
No; they are not the same thing. The rock cycle takes place on a VERY long time scale.. hundreds of millions of years, and involves all of the earth's crust returned to the core of the Earth, to return later as lava.
The phosphorus cycle is the recycling of phosphates into living things as a result of erosion, participation in life processes, and the return of dead biotic material to the soil.
