Answer:
Seawalls are made for coastal defense purposes
Explanation:
Seawalls are massive structures which are designed to prevent coastal erosion and other damages due to wave action during huge storms such as hurricanes.
My family used to live near one. It are very satisfying to watch during rain storms, because you can hear the sound of the rain falling on top of it. I also loved watching the waves hit the sea wall then roll back down.
Hope this helps. ( Sorry I go a little carried off)
