A fossil reef is a type of reef that forms from non-living materials, such as ancient coral structures that have turned into rock over time. These reefs provide valuable insight into Earth's past environments and can be found in various locations around the world.

Fringing Reef
Microscopic Algae live in coral reefs
Fringing reefs form very close to the shoreline of a volcanic island. They are the most common type of reef and directly attached to the shore without a lagoon separating them.
Barrier reefs form parallel to the shoreline but are separated by a lagoon.
Barrier reefs form parallel to the shoreline but are separated by a lagoon.
The Great Barrier Reef is a coral reef.
Fringing reefs are reefs that are usually found close to the shore of continents or around islands and forms as a long bar attached to the land. The Great Barrier Reef is an example of this.
A fringing reef is a type of reef that closely borders the shoreline and is separated from the land by shallow water.
Land forms
A circular reef that forms above a guyot is known as an atoll. Atolls typically develop around the rim of a submerged volcanic island, with the lagoon in the center. Over time, as the island erodes and sinks, the coral reef continues to grow upward, maintaining its circular shape. This unique structure supports diverse marine ecosystems and is often found in tropical ocean waters.
