What is a rocky platform?

Answer 1

These are formed by waves eroding

the rock face between high and low tide. The

erosion causes a notch to form at the base of

the rock face, where the waves strike it. As the

notch becomes larger, it undercuts the rock face

and a rocky platform develops beneath it. This

undercut section eventually becomes weak and

collapses. Over time, this process is repeated

many times. The cliffs gradually retreat inland

while the rocky platform extends further into

the sea.
