explain how spits form.

constructive waves approach at an angle to the beach. the strong swash pushes the sediment up the beach however the weak backwash pulls it back at a right angle to the coast. the longshore drift current transports the sediment. the sediment builds up at the end of the beach

explain how stack like old harry form.

old harry is a sea stack found in dorset. the head which is made of chalk juts out into the sea. at high tide the destructive wave erodes the headland through hydraulic actionand corrosion. lines of weakness in the headland are enlarged by erosions forming a cave. if there are caves on both sides of the headland and they erode through it, it forms an arch. over time the arch becomes too heavy and collapses leaving an isolated feature known as a stack.
