According to Daly’s glacial control theory, during the last glacial period the formation of ice caps lowered the ocean level by 60 to 70 meters below the present surface. Waves cut the shores to make flat platforms suitable for growth of coral. As the ice caps melted and temperature rose, corals began to grow on these platforms and rose upwards with rising ocean levels, and all type of reef were formed on the pre-existing platform. There is evidence that coral reef is growing today on submerged land and the foundation of reef are now at a much greater depth than they were when corals first began to grow.
