The Blue Hole

The Blue Hole is a large, circular underwater sinkhole or cavern, often found in coastal or reef areas. Formed through natural erosion over thousands of years, these geological features are characterized by their deep, clear blue waters and steep walls. They attract divers and snorkelers for their unique beauty and marine life. Blue Holes can vary in size and depth; some are hundreds of meters wide and deep. They are important for scientific study, offering insights into Earth's history and climate, as well as serving as vibrant ecosystems for diverse marine species.
