How Do You Spell BLOWHOLE?

1. A Blowhole can refer to two distinct definitions depending on the context in which it is used.

   When referring to marine mammals, particularly cetaceans such as whales or dolphins, a blowhole is a specialized opening on the top of their heads used for breathing. These unique structures act as the equivalent of a mammal's nose, allowing them to inhale and exhale the air they require to survive while submerged underwater. Blowholes are designed to close when the animal is submerged, preventing water from entering their respiratory system and ensuring efficient respiration upon surfacing. The size and shape of a blowhole can vary depending on the species, with some having a single blowhole opening while others have two.

   In a geological context, a blowhole is a natural cavity or opening found in coastal rock formations that connects to an underground cave or tunnel. These formations are typically formed by the eroding action of waves, resulting in a vertical tunnel-like structure. Blowholes often have an opening at both ends, enabling the seawater to surge into the cavity and create a spectacle when the high-pressure water is forced upward and ejected through the top opening, resembling a geyser. These geological phenomena are frequently visited by tourists due to their impressive and captivating displays of splashing water.
