Coastal Landforms

Coastal erosion produces beautiful beaches and some rather unusual land formations, from spits to stacks, mud flats to salt marshes.

Earth Science - Geology - Learning Points.

Cliffs are formed when destructive waves attack the bottom of rock faces.

Weak points in the rock give way to a hollow called a wave-cut notch.

The cliff retreats and eventually the overhanging rock collapses, forming a wave-cut platform.

Beaches are built up as sand, pebbles, and rocks are deposited by constructive waves.
