Explanation: 

Detailed explanation-1: -Phosphorus can be found on earth in water, soil and sediments. Unlike the compounds of other matter cycles phosphorus cannot be found in air in the gaseous state. This is because phosphorus is usually liquid at normal temperatures and pressures. It is mainly cycling through water, soil and sediments.

Detailed explanation-2: -Most of Earth’s phosphorus is stored as phosphate in rocks and in the soil. Specifically, the form of rocks that phosphorus can be found in is sedimentary rocks on earth and in the ocean.

Detailed explanation-3: -On land most phosphorus is found in rocks and minerals. Phosphorus-rich deposits have generally formed in the ocean or from guano, and over time, geologic processes bring ocean sediments to land.
