Geology and Rock Type The most important feature of a coast is often the type of rock in the area. Some rocks are resistant to erosion, whereas other rocks.

Think, Pair, Share You have been learning about geology/rock types, geological structure and shape of the coastlines. We are going to build on that knowledge further. We must understand the rates of erosion at the coastline or rates of recession. In pairs write down the factors that influence how fast the coastline moves inland. Think, pair, share!
