Beach erosion is when wind, water, and ice take away sediments of land. When earthquakes occur on areas with steep slopes many times the soil slips causing landslides. Human activities have always been a main cause of land slides throughout the world. In California and Virginia have no rocks and it is eroding quicker then Maine's coast.
I think people should add rocks to beaches because sand goes a lot quicker then rocks go. Kinda like Maine's coast there is a lot of rocks unlike California's coast all they have sand and nothing els. That is why it goes quicker then Maine's coast. I think people should make this a bigger deal then it is because if we add sand to beach's that is not good. What if we run out of beach sand what will happen then? That is why we should make it a bigger deal.
