What Are Sea Arches?
Arches form at headlands where rocky coastlines jut out into the sea. Powerful waves pound into rock from both sides of the headland. The waves erode (wear away) the rock at sea level to form sea caves on either side. The waves eventually break right through the headland creating an arch.
What is a sea arch in geography?
[′sē ‚ärch] (geology) An opening through a headland formed by wave erosion or solution (as by the enlargement of a sea cave or by the meeting of two sea caves from opposite sides) which leaves a bridge of rock over the water.

Sea arch is a natural opening eroded out of a cliff face by marine processes. Somearches appear to have developed from surge channels which are created by wave refraction causing the focussing of wave fronts on the side of a headland. … The architecture of an arch is a reflection of its lithology and structure.
