Today I went diving in the sea. I wanted to look at the coral reefs, which are a bit like underwater mountains. The coral reefs often surround the islands and help to stop the waves crashing onto the beach. The strong sea can sometimes damage the coral. I saw a lot of coral that had been broken. It is easy to understand how much damage the waves could do to the islands if there was no coral reefs to stop them. |  |
