How Caves Form

Waves crashing against the base of a cliff can sometimes form a sea cave.

Sea caves form along a crack in a rock or an area where the rock is softer.

Because the abrasive action of waves is concentrated at the base of the cliff, an overhang forms. This effect is more pronounced when the rock beds that comprise the cliff are slanted.

Sea caves are typically found in sandstone but also appear in other types of sedimentary rock, including limestone. They are less commonly formed in harder rock such as granite.
