Question

what is the seawall protecting the coastline from in this image? earthquakes mudslides wave action tidal surge

Explanation:

Seawalls are structures built along coastlines to protect against the erosive and destructive forces of waves and high - energy water movements. In the image, the large waves hitting the seawall indicate that it is protecting the coastline from wave action. Tidal surges are also related to water movement but are more associated with storm - related sea - level rises. Earthquakes and mudslides are not directly related to the function shown in the image.
