Susan is a geological researcher measuring the rate of removal of phosphorous from sedimentary rock during the phosphorous cycle. what process is susan investigating? mineralization eutrophication weathering decomposition

The correct answer is weathering.  

The dissociation of soil, rocks, and minerals, as well as wood and artificial components via exposing with the atmosphere of the Earth, biological species, and water, is known as weathering.  

In the phosphorus cycle, the phosphorus moves in a cycle via water, rocks, sediments and soil, and organisms. In this cycle, with time, the process of weathering and rain makes rocks to discharge phosphate ions and other minerals. This inorganic phosphate then gets dispersed in water and soils.  

The answer is weathering.

Weathering is the breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters.
