Landon is investigating the coastal area near where he lives. He has found that one end of the coastal area without barrier islands is losing beach area, but the other end that is bordered with barrier islands has a beach area that has remained the same size. Why is the size of the beach decreasing on the end without barrier islands?

Explanation:

Barrier Islands act just as the name states, they are barriers that protect the beaches. They exist to absorb the majority of the external energies that waves, hurricanes, storms, etc. Without it, the beaches begin to become absorbed by the ocean, due to the destructive energy these factors apply, as well as eroding away all rocks into the ocean. This is mainly why the beach with a barrier island is completely protected while the one without a barrier island is decreasing in size.
