The type of the rock- how resistant is it to erosion/weathering?

The dip of the rock strata- which way do they face?

The number of joints between rocks layers, these are susceptible to erosion and

weathering.

Likely to erode more slowly.

Have tall and vertical cliffs.

Have features such as arches and

stacks.
