Which of the following is one way that beach erosion can occur?
1.currents increasing the sand on the beach with additional sand from the ocean
2.storm waves bringing sand to the beach from the ocean
3.storm waves pulling sand from the beach out into the ocean
4.currents replacing sand on the beach with sand from the ocean

i believe its 3 because when erosion happens sand goes away it does not come back
