Final answer:
The Canadian Maritimes are the regions in Canada most susceptible to coastal erosion due to factors like poor soil quality, harsh climates, and less protection from waves. The Bay of Fundy, known for its tidal flats, is another area affected by erosion partly due to the loss of sea ice shielding the beaches.
Step-by-step explanation:
In Canada, the areas most susceptible to coastal erosion are the Canadian Maritimes, which include New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland, and Labrador. The coastal erosion in these regions is influenced by several factors including the poor soil quality due to glacial activity, exposure to harsh climates, and the orientation of coastlines that may not protect them sufficiently from waves. Moreover, the Bay of Fundy in Nova Scotia is noted for its tidal flats composed of silt and clay, which are affected by the tides and are low energy environments, contributing to the potential for coastal erosion. Additionally, the loss of sea ice, which normally shields beaches from waves, exacerbates the erosion of the coastlines, especially in regions , such as the Arctic coast of Canada.
