Active Marine Erosion Cliffs

      Active marine erosion cliffs refer to the steep rock cliffs distribute along coastline, they are the most conspicuous, the most spectacular and the most characteristic landform landscapes on Weizhou Island. Marine erosion cliffs are formed by waves, gravity and tectonism. During tide periods, erosion caused by waves on coastline is continuously strengthened, bedrocks on coastline are rushed constantly and form caves – marine erosion caves. As marine erosion caves gradually get deeper, bedrocks on coastline collapse under gravity, when there are joints, fractures and other structural planes, rocks collapse along fracture and joint planes and form steep cliffs, coastline continuously retreats, collapsed rocks are constantly abraded by tides and waves and finally appear as fragments on sand beach.
