  7. 7. Exposed lines of weakness in ______ allow Hydraulic Action to form _____small along the base of the cliff. Over time the cave will continue to grow through _______ ______ and meet another cave on the other side of the headland forming a small ______. ______ will continue and undercut the base of the arch until it eventually falls due to lack of support and _______. This leaves behind a stack which will eventually collapse due to ___________and gravity to leave a _____. erosion stump undercutting gravity caves Hydraulic Action arch cliffs
  8. 8. Identify the Coastal Landforms 1. 2 3 4 5 6
  9. 9. Caves, arches, stacks and stumps 1. The waves erode FAULTS (cracks) in the headland. 2. The waves eventually erode through the headland to form an ARCH . 3. The arch becomes unsupported and collapses to form a STACK . 4. A STUMP is formed from the collapsed stack. C D B A Match the image with the most appropriate label. 1 2 3 4
