Why is phosphorus and sulphur cycle called as sedimentary cycle?

Expert Answer:

Sedimentary biogeochemical cycles are systems in which the reservoir is in the crust of the Earth. They are slow and less perfect systems as their elements may get locked on the reservoir pool and may go out of circulation for long periods. Since elements such as phosphorus and Sulphur are abundant in the Earth's crust, they have sedimentary cycles.
