Coastal Processes and Landforms
Coastal Processes and Landforms Coastal Processes and Landforms
The force of the waves hitting a cliff compresses water and air into cracks and joints.This can be equivalent to 30,000 kg/m 2 . This increase in pressure may lead to crackswidening and pieces of rocks breaking off.
Rock fragments may be picked up bywaves and thrown against the rockface by subsequent waves.The effectiveness of the corrasiondepends on the strength of thewave, the nature of its “load” andthe resistance of the rock in the cliffface.Corrasion is most effective at thebase of cliffs.
