Coral Reefs

   Coral reefs are very beautiful and interesting marine miracle. Travelocity Promotional Code will help you explore this area perfectly. My son is very interested underwater world after our last year vacation tour on Hawaii. Especially he is wondering of coral reefs. Early I have never been interested in this question, but after my son's passionate desire to get to know as more as it possible about it, unwittingly I also took an interest in this. In actual fact there are builded islands, but it is build not by people, and by small ocean dwellers – coral polyps. They produce a lime from sea water and build from it their little houses. These little marine builders live not at a great depth, in light and warm water, either near the coast, or at peaks of underwater mountains. There are uncounted polyps underwater. Having lived their life, polyps perish, and on the empty houses other polyps build new houses. From heaviness of the upper constructions the lower become break, pressed and stick together. Century passes, and at the peak of underwater mountain appear beautiful constructions. If the earth raise underwater mountain on a little and its peak appears over the water surface. It is arise coral reefs – chains of coral rocks and even small islands. It is a really interesting to research this natural phenomenon and my son persuaded me to the next summer make a tour on a seacoast.
