Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Stacks Figure 7 showing Stacks. This landform was present at Robins Bay, Don Christopher Cove and Peytons Point. 14 Don Christopher Cove and Don Christopher Point Landforms: y Platform y Cliff y Cove y Beach y Inlet y Stack (Figure 6) y Headland (Figure 5) Comprised of Mainly: y Sand y Shingle The Cove was filled with deposit materials.

Cliffs are formed as erosion landforms due to the processes of erosion and weathering that produce them. Cliffs are common on coasts and along rivers. Cliffs are usually formed by rock that is resistant to erosion and weathering. Sedimentary rocks are most likely to form sandstone, limestone,
