what is a blowhole?

Answer 1

Any hole through which water, steam or air comes. Whales and dolphins have blowholes. Old Faithful geyser is a steam/hot water blow hole. There are places on the coats where the waves have made holes up through rocks so that at high tide the waves come up through the hole. Caves sometimes have small holes that go up through the ground far from the cave entrances.

Then there are blow holes in flutes, pipes and other wind instruments.

Answer 2

In geology, a blowhole is a cavity formed in the ground at the inland end of a sea cave. When waves enter the mouth of the cave they will be funneled up towards the blowhole, which can result in quite spectacular splashes if the geometry and state of the weather is appropriate. See Category:Blowholes for a list of blowholes.
