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 . Chalk cliffs at Flamborough head. http://www.flickr.com/photos/moonrising/2478441695/

Likely to erode more quickly. Have lower cliffs, with shallower inclines. Clay cliffs at Mappleton. http://www.flickr.com/photos/vikellis/2811526189/ Have features such as beaches .

The number of joints within rocks will also influence the resistance to erosion and weathering . Bed joint

The angle of dip of the rock strata will influence the shape of the cliff. How will this cliff change in shape with erosion ?
