Question: What are corals? How do they help in formation of coral islands?

Answer:

• Coral are tiny marine animals. They are called polyps.

• When the living polyps die their skeletons are left. Other polyps grow on top of the hardened skeleton which grow higher and higher in course of time. Thus coral islands are formed.
