Question

Where are almost all living coral reefs found?
Surrounding the North American continent
Within 40 meters of the surface of the ocean

Answer 1

Almost all living coral reefs are found within 40 meters of the surface of the ocean. They typically thrive in warm, shallow waters of tropical and subtropical regions, where conditions are ideal for coral growth. This depth allows them to receive enough sunlight for the symbiotic algae (zooxanthellae) that live within coral tissues to perform photosynthesis.
