A blowhole is a cavity formed when a joint between a sea cave (formed by erosion) and the land surface above the cave becomes enlarged. The sea cave and the land surface become conjoined when the roof of the cave collapses. Blowholes are formed by the process of erosion. When waves enter the mouth of the cave they will be funneled up towards the blowhole, which can become quite spectacular if the geometry and state of the weather are appropriate.
