Costal area- Dorset coast 0.0 / 5 ? GeographyCoastal zonesGCSEOCR Created by: Sharla16Created on: 23-04-17 13:36 Why does the Dorset coast have so many landforms? It's made of bands of hard rock and soft rock, which erode at different rates. 1 of 6 Name an arch and how it was formed? Durdle door. Erosion by waves opened up a crack in the limestone headland, which eroded into a cave then eventually an arch. 2 of 6 Name a cove and how it was formed? Lulworth cove. A gap was eroded in a band of limestone, behind the limestone is a band of clay which the water eroded away to form a cove. 3 of 6 Name a tombolo and how it was formed? Chesil beach. Formed by longshore drift, joins isle of Portland to the mainland. 4 of 6 Name the two bays and the headland between them? Swanage bay, Studland bay, The foreland. The bays are areas of softer rock (sandstone and clay) and the headlands made of chalk. 5 of 6 Name a stack and stump? Stack- old Harry. Stump- old Harry's wife. The end of 'the foreland' eroded to form these. 6 of 6
