Concentrated energy from wave erosion flattens or straightens the coastline.
<u>Explanation:</u>
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.
as the ocean plate is pushed under the overriding continental plate the ocean sedimentary layers are heated compressed and melted the pressure of the converging plates that create the subduction zone forces the Continental play upwards creating mountain ranges such as Andes
