Describe the formation of a blowhole

  

Answers


Faith
On the landward side if a cliff, a vertical hole may develop. This could be as a result of chemical weathering of the rock along the joints. The rocks along those joints may have been eroded and dissolved causing the joints to enlarge. If this hole appears on the roof of the cave it becomes a blowhole. It is a blowhole in the sense that, as the waves break inside the cave during high tide, some water may forced through this shaft. The water may therefore be seen shooting out of this hole. This causes the hole to widen further.
