The correct answer is Waves can cause shifting shorelines.
Waves have a direct impact on the movement and shaping of shorelines. When waves approach the shore, they carry energy and sediment. As the wave approaches the shore, the bottom part of the wave slows down due to friction with the seabed, causing the top of the wave to keep moving forward, eventually crashing onto the shore.
This process is known as wave breaking, and it has a significant impact on the shoreline. When waves break, they transfer energy to the shoreline, resulting in erosive processes like abrasion, hydraulic action, and corrosion. These processes can wear away the shoreline material and cause it to shift or retreat over time.
The intensity and direction of waves play a crucial role in determining the direction and rate of shoreline movement. Strong and powerful waves tend to erode the shoreline more rapidly, whereas weaker waves may deposit sediments and build up the shoreline.
Therefore, it is accurate to say that waves can cause shifting shorelines due to their erosive power and sediment transport.
