Marine Terraces Marine terraces are formed by coastal erosion and reflect the history of the rise and fall of sea level over time. However, marine terraces are only found along coastlines where the land is rising. In areas where the land is sinking they are submerged or buried by younger sediments.
Wave cut platforms. The sea cliff is the most widespread landform of coastal erosion. Cliffs begin to form when destructive waves attack the bottom of the rock face between the high and low water marks. By the wave processes such as hydraulic power and abrasion, the waves undercut the face forming a wave-cut notch.ave cut platforms. The sea cliff is the most widespread landform of coastal erosion.
