The correct option is C.

The geochemical cycle refers to the pathway through which certain chemical elements pass on the surface of the earth and underneath the surface of the earth. The cycle is described as geochemical because it involved both the geological and chemical factors. The three major geochemical cycles that exist on the earth are hydrologic, rock and tectonic cycles. The hydrologic cycle deal with the movement of water round the earth surface, both underneath and on the surface of the earth, the rock cycle deal with rocks while the tectonic cycle deal with rock deformation process.
