Resistant Rock
Hard Igneous rocks e.g Basalt and Granite (Iceland)
1 of 9
Fairly Resistant
Sedimentary rock e.g Sandstone, Chalk and Limestone (Dover)
2 of 9
Less Resistant
Soft- weak sedimentary e.g clay and shale -these erode fast (East Yorkshire)
3 of 9
Hard Rock Coastline
High Steep Cliff, often bare with little rock loss and few boulders at the bottom (Cornwall)
4 of 9
Soft Rock Coastline
Less rugged more shallow cliffs, May have piles of slipping mud and clay with few rock some sand and mud at the foot of the cliff.
5 of 9
Hydraulic Action
Resulting from the force of the water hitting causing pockets of air int cracks and crevices in the cliff face.
6 of 9
Abrasion
Waves picking up stones and hurling at the cliff, therefore wearing the rock away.
7 of 9
Corrosion
Chemicals in the water dissolving the rocks
8 of 9
Atrition
Any material carried by the waves will become rounder and smaller over time as they collide with particles. the sharp edges get worn off.
