In case of which one of the following biogeochemical cycles, the weathering of rocks is the main source of release of nutrient to enter the cycle?

The Phosphorus cycle is a sedimentary cycle where the primary reservoir is the Earth's crust, and weathering of phosphate-rich rocks is the fundamental process that releases nutrients into the soil and water. While the Sulphur cycle also involves a sedimentary phase, it is considered a hybrid cycle because it has a significant gaseous component (e.g., $SO_2$ from volcanoes), whereas Phosphorus lacks a prominent atmospheric phase. This question tests the classification of biogeochemical cycles into gaseous and sedimentary types based on their primary reservoir.
