In the phosphorus cycle, phosphorus primarily exists in the form of phosphate (PO₄³⁻) in rocks and minerals. Over time, these rocks undergo weathering, releasing phosphate into the soil and water, where it can be taken up by plants. However, to complete the cycle and return phosphorus to its geological reservoir, new rocks must be formed.

The formation of new rocks through heat, time, and pressure is part of the rock cycle, where sedimentary r...
