A blowhole system always contains three main features: a catchment entrance, a compression cavern and an expelling port. The arrangement, angle and size of these three features determine the force of the air to water ratio that is ejected from the port. [6] The blowhole feature tends to occur in the most distal section of a littoral cave. As ...
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.
Blowhole may refer to: Blowhole (anatomy), the hole at the top of a whale's or other cetacean's head; Blowhole (geology), a hole at the inland end of a sea cave Kiama Blowhole in Kiama, Australia; The Blow Hole, a marine passage between Minstrel and East Cracroft Islands in the Central Coast of British Columbia, Canada
The blowhole is most active when the tide is high and the winds are strong, [3] and it can shoot sea spray up to thirty feet high in the air. [ 4 ] Hālona Point is a tourist spot, with visitors coming for the scenery, the beach at the cove, and in the winter as a spot to go to see humpback whales or Honu turtles (Hawaiian Green Sea Turtles).
The Pancake Rocks are a heavily eroded limestone formation where the sea bursts through several vertical blowholes during incoming swells, particularly at high tide. The limestone was formed in the Oligocene period (around 22–30 million years old), a period in the geological history of New Zealand where most of the continent of Zealandia was submerged beneath shallow seas.

In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales , these are in pairs. It is homologous with the nostril of other mammals , and evolved via gradual movement of the nostrils to the top of the head. [ 1 ]
The storylines converge when George and the woman take a stroll on the beach only to come across a beached whale that he discovers has a golf ball in its blowhole after he is pressed into saving it.
A water resources borehole into the chalk aquifer under the North Downs, England at Albury. Engineers and environmental consultants use the term borehole to collectively describe all of the various types of holes drilled as part of a geotechnical investigation or environmental site assessment (a so-called Phase II ESA).
