Weathering processes are continuous at all times on the earth's surface. Rocks are weathered both through mechanical and chemical processes as rock material changes composition or becomes chemically altered into smaller pieces, ultimately reaching physical and chemical balance. Mechanical weathering, such as frost wedging and exfoliation processes work to physically break down rock and expose larger surface areas which accelerates the physical and chemical reactions brought on as the result of chemical and mechanical weathering. Examples of mechanical weathering include the reaction of atmospheric CO2 and water (carbonic acid) frost wedging and tree roots disrupting curbs and breaking through solid rock. Chemical weathering results in the formation of clay particles. For example, the reaction of carbonic acid with solid granite can completely alter feldspar minerals into fine-grained quartz materials, In fact, chemical weathering ultimately reduces solid rock material into clay particles over time. An example of chemical weathering can be as simple as a rusted nail.

Describe the differences between mechanical & chemical weathering Processes. (see attahed file)
