B. changes in the appearance of the earth’s surface.

Weathering is the physical or chemical breaking down of the Earth's surface. This includes rocks, soil, minerals, wood, and artificial elements that are exposed to the Earth's atmosphere, water and biological organisms. The process is different from erosion because erosion requires the transportation of materials which are then deposited somewhere else. On the other hand, weathering occurs in the same place, with little or no movement of material.
