Describe the process of reef formation, including the destructive and constructive phases
What will be an ideal response?
The process of reef formation involves a destructive phase and a constructive phase. During the destructive phase boring organisms will drill into the base of a coral head where sunlight is weak. Because of the low sunlight, the coral cannot repair the damage and storms can now easily break the coral head off its base. Loose coral is pulverized by wave action and new corals grow on top of the rubble during the constructive phase. Red and green algae play a role in cementing the pieces of coral together with wet calcium carbonate.
