Reef Formation

Reef formation involves the buildup of limestone structures primarily created by corals and other marine organisms. Corals, tiny animals, secrete calcium carbonate to form hard skeletons that accumulate over time. As these skeletons grow and die, they pile up and harden, developing into reefs. Additional organisms like algae and shellfish contribute to this structure, enhancing its complexity. Reefs typically form in shallow, warm, clear waters where sunlight can reach, supporting the photosynthetic organisms that live there. Over thousands to millions of years, these processes result in the vibrant, extensive coral reef ecosystems seen today.
