Coral Reef Teacher’s Guide What and Where are the Coral Reefs?
REEF FORMATIONS
The dotted areas represent coral.
1) This is a fringing reef where coral
grows directly from the shoreline.
2) This is a barrier reef which is separated
from shore by a lagoon.
A barrier reef forms as the island sinks.
3) This is an atoll. Atolls form when the
island sinks below the water, leaving
a ring of small sandy islands and coral
reefs around a central lagoon.
Color the fringing reef red, the barrier reef orange, the atoll purple, the
land green, and the water blue.
