When to talk about the plate tectonic it sound the same as our continents as we see in the ancient days you were having two continents which is laurasia and Gondwanaland
The answer is friction. As ocean wave approach the shoreline, they are affected by the sea bed through process such as refraction, shoaling, bottom friction and wave-breaking. However wave breaking also occurs in deep water when the waves re too steep. If the waves meet major structurer or abrupt changes in the coastline, they will be transformed by diffraction.
