The back and forth movement erode the coastline
Let understand that "Coastline" is the area where the land meets the ocean. In some places, a coastline serves as beaches for entertainment.
- Ocean waves keeps moving back and forth the coastline leading ro gradual erosion of the coastline particles into the ocean
- Also, the Destructive waves have stronger back-washes and thus contribute to larger eroding agent for coastline because the force of the water removes the top layer with force.
In conclusion, the back and forth movement of the water continually loosens the sediment on the coastline till they get smoother and then eroded into the water.
