Notches, Cliffs and Wave-cut Platform COASTAL FEATURES Notches, Cliffs and Wave-cut Platform
NOTCHES & CLIFFS A notch is cut in the rock at the level where wave attack is concentrated. When the notch is cut too far, the area above this notch collapses forming a cliff. A cliff is defined as a steep rock face. Where marine erosion is powerful, the coastline is eroded to form a cliff. Erosion is concentrated at sea level.
CLIFFS & WAVE-CUT PLATFORMS The process of erosion continues and the cliff retreats further and further back. As the cliff retreats, a flat area which is exposed at low tide is left at its base. This feature is known as a wave-cut platform. https://www.curriculumbits.com/prodimages/details/geography/cliffs-and-wave-cut-platforms.html
GROUP ACTIVITY Sort these statements into two sequences (one for abrasion, one for hydraulic action) to show how cliff erosion takes place. How does the waves erode cliffs? Draw a series of 2-3 diagrams, using every statement to label them, to show how cliff erosion takes place.
