Describing a Fringing Reef
A fringing reef can grow… on the outer edge of a land mass
- This means a fringing reef can grow very close to shore
OR
directly from the shore- This means a fringing reef can grow
directly off of the shore into the ocean. Therefore, this type of fringing reef is attached to the shore
Hmm…What does a fringing reef look like?

Describing a Fringing Reef
Mr. and Mrs. Fringing Reef have a lagoon?... Or not?
lagoon: water separated from open water by a sandbank or a coral reef
A fringing reef can have:
a very shallow lagoon
OR
no lagoon at all
Do raccoons swim in lagoons?

Barrier Reef
Barrier Reef
Welcome to a barrier reef!
Describing a Barrier Reef
A barrier reef is located much further away from the shore than a fringing reef.
A barrier reef:
• runs parallel to the shore
• is always separated from the shore by a lagoon
lagoon: water separated from open water by a sandbank or a coral reef

Barrier reefs always have lagoons !

This is an example how what a barrier reef usually looks like.
Notice how the barrier reef would always be parallel to the shore no matter what part of the shore you stand on.

Patch Reef
Patch Reef
Welcome to a patch reef!
Describing a Patch Reef
Previous
NextMain Menu
Patch reefs are only able to form and grow in lagoons.
Patch reefs are smaller patches of coral reef that can only be found within large lagoons. Patch reefs often form in the lagoons of barrier or atoll reefs.
lagoon: water separated from open water by a sandbank or a coral reef
Patch reefs:
• mostly form as circular patches of coral reef
• surrounded by sand or sea grass
• are very common

Atoll Reef
Atoll Reef
Welcome to a atoll reef!
Describing an Atoll Reef
Previous
NextMain Menu
Patch reefs would not exist if a barrier reef had not formed first.
It takes thousands of years for an atoll reef to form. An atoll reef forms when the landmass/island had completely deteriorated, leaving a barrier reef surrounding a large lagoon which makes it an atoll reef.
Atoll reefs:
• circular or horseshoe-shaped
• surround a central lagoon
• no landmass or island
Picture an Atoll Reef
Central lagoon where landmass or island used to exist.
This is an example how what an atoll reef looks like.If there was a landmass or island in part of the lagoon, this would be a barrier reef.
