what is wave erosion ?
Answers
Answer:
Landforms Created By Wave Erosion. The softer rock along the coastline erodes first. Sometimes waves can erode a hollow area called a sea cave. Over time waves can also erode the base of a cliff so much that it makes the rock above it collapse, creating a wave cut cliff.....
Explanation:
Waves are the major cause of erosion along the coast. Waves shape the coast through erosion by breaking down rock and moving sand and other sediment.
Picture
How Waves Erode
One way waves erode the land is by impact. Large waves hit rocks with lots of force. The energy in waves can break apart rocks. Over time waves make small cracks bigger. Eventually the wave causes the rock to chip off. Waves can also erode rock by abrasion. As a wave comes to shallow water it picks up sediment. Once the wave crashes against land the sediment wears the rock down.
As a wave approaches land it usually changes direction due to the way the wave drags on the bottom. When these waves change direction they can create a headland. A headland is a part of the shore that sticks out into the ocean. The headland sticks out from the shoreline because it is made from harder rock than the rest of the coast, making the shore erode before the headland.
