Learn about coral reefs in our coral reef facts for kids. What are coral reefs and where are they found? What lives inside coral reefs?
Reefs are the big cities of the sea. They exist because the growth of corals matches or exceeds the death of corals – think of it as a race between the construction cranes (new coral skeleton) and the wrecking balls (the organisms that kill coral and chew their skeletons into sand).
Students will identify the relative depth of corals in the ocean by observing the behavior of cold and warm saltwater in an experiment. Students will gain a global understanding of coral reef life by reading for information and creating a model of a reef.
A coral reef is a structure in shallow ocean areas that is formed mainly by stonelike coral skeletons. Corals are small marine animals that live in all oceans of the world. Some individual corals, called polyps, are colonial, which means they grow together in large groups called colonies. As they die, they leave behind their skeletons.
