In geology, a blowhole or marine geyser forms as a sea cave grows landward and upward into a vertical shaft that breaks through toward the surface. This can cause hydraulic compression of seawater, which is released as spray through the opening at the top. The height of the spray is governed by the geometry of the cave and blowhole together with tide levels and swell conditions.
