Answer:
Seawall
Explanation:
A seawall is a structure that is built so that it can serve as a form of defense for the coast against disasters such as erosion due flooding, high tidal waves, tsunamis and severe storms.
A seawall serves as a form of separation between the land and the sea. It helps to protect humans and their houses from destruction.
A seawall is constructed using concrete, steel or wooden materials. It is built parallel to the shore. It can be shaped in the form of a slope or a block.
