Question

Susan is a geological researcher measuring the rate of removal of phosphorous from sedimentary rock during the phosphorous cycle. What process is Susan investigating?

Answer 1

the process Susan is investigating is weathering

Answer 2

Weathering

Step-by-step explanation:

Weathering of rocks releases phosphorus in soil. The phosphorus is used by plants and reaches into animal bodies when animals feed on plants and plant products. Part of phosphorus present in soil is carried to water by surface runoff and is incorporated into sediments. Gradually, phosphorus becomes part of sedimentary rocks. Hence, removal of phosphorus from rocks occurs by the process of weathering.
