Answer:
D) Erosion and Weathering
Step-by-step explanation:
Erosion forces rocks to crash together or crack apart, some rocks shatter and crumble, while others are worn away.
During erosion, exfoliation which is a type of weathering occurs in sheets along joints/ lines which runs throughout Stone Mountain. Once a sheet on the surface has been exfoliated and the sheet of rock beneath it is exposed the process begins again. This process gradually changes the way Stone Mountain looks.
