Large, lithified formations of calcium carbonate formed from both living and skeletal coral colonies are called coral reefs. Barrier islands are narrow islands that parallel the coastline and are separated from the mainland by a shallow sound, bay or lagoon. Atolls are circular coral reefs that surround a lagoon, and tombolos are narrow sandbars that connect an island to the mainland or another island.
