Answer:

Below are some bullet points describing some of the many influences of geology on coastal erosion.

Step-by-step explanation:

  • Harder more erosion-resistant rocks will slow the rate of erosion while weaker and more erodible rocks facing the sea will speed up the rate of erosion.
  • Erosion is greater on those continental margins along subduction zones and tectonic plate borders because the continental shelf is almost non-existent.
  • Erosion is lesser on coasts located in the middle of tectonic plates because of the presence of an extensive continental shelf with reduces wave height and lowers the erosion rate.
  • The presence of loose material and debris on beaches can create an important obstacle to wave action that minimizes and dramatically slows erosion of a beach or coast.
