Answer 1

A barrier reef is a carbonate reef that forms a barrier to waves along a coast. It is often located further offshore compared to other types of reefs and helps protect the shoreline from erosion and wave action.

Step-by-step explanation:

A barrier reef is a carbonate reef that forms a barrier to waves along a coast. It is often located further offshore compared to other types of reefs. Barrier reefs can be found in areas where there is either a very narrow back reef area or none at all. These reefs are typically parallel to the coast and help protect the shoreline from erosion and wave action. An example of a barrier reef is the Great Barrier Reef in Australia.
