What contributes to coastal erosion?

  1. Low tides only

  2. High tides only

  3. Human activity and natural processes

  4. Ice formation

The correct answer is: Human activity and natural processes

Coastal erosion is the process of removing sediment, rocks, or soil from the coastline. This can be caused by a variety of factors, including tides, human activity, and natural processes. Low tides (option A) only contribute to erosion in certain areas and at certain times, while high tides (option B) can also play a role in removing sediment and shifting the coastline. However, human activity and natural processes (option C) have a much greater and long-lasting impact on coastal erosion. Human activities such as construction and development, as well as natural processes like weathering and wave action, can accelerate the erosion process and lead to the loss of coastal land. Ice formation (option D) can also cause erosion in some polar regions, but it is not a major contributor to coastal erosion overall. This is why option C is the correct answer for what contributes to coastal erosion
