Whee the physical and the chemical play a major role in the breaking and wearing down of the surface of the earth's crust. Thee two causes led to erosion and hence the impacts of the winds and the water and thus they onset the stage for the process of the chemical weathering to take place that is moved with oxidation and the hydrolysis of the surface of the earth. Further biological wearing by the organism and the mand has a significant impact on the erosion process.
