A combination of geological structure and sea level riseproduces the morphology of landforms aligned parallel to the coastline. As the wave approaches a coast, its progress is modified due to friction from the seabed, halting the motion of waves. There are four major different types of coastlines: Below, we will go into more detail on all of these different types of coastlines. On discordant coastlines, differential erosion may occur, where bands of hard and soft rock outcrop at right angles to the sea.
