Geology refers to strata (different layers of rock), deformation (tilted or folded) by tectonic activity and faulting
Igneous rock- very seorsionsion rates (Granite) are crystalline/interlocking crystals . Granite has few joints
Sedimentary rock - Moderate to fast erosion rate (sandstone and Limestone) most are clastic and erode faster, age of rock is important (young will be weaker) many have bedding places and fractures
