6. What effect will the concentrated energy from wave erosion eventually have on the shape of the coastline?

Concentrated energy from wave erosion flattens or straightens the coastline.

Explanation:

When waves move, they carry with them energy. This energy is transferred by the moving water to the coastline. When the waves hit the coastline, they cause erosion.

The erosion of the coastline takes place on a regular basis because waves keep hitting the shoreline. This erosion eventually causes the coastline to become straight because erosion takes away with it sand as well as rocks that form the irregular shape of the coastline.

The shoreline becomes flatter.

Explanation:

The effect that the concentrated energy from wave erosion eventually have on the shape of the coastline is the shoreline would become flatter.
