Describe the four natural forces that can cause erosion. How do they work? Explain your answer in at least three sentences.

Answer:

Responses may vary but should include some or all of the following information:Erosion is the process of rock and sediment being carried away from its original location. Gravity can cause erosion, as broken-down rock can fall or move downhill. Another force is wind; wind can crash against rock, sand, or sediment, and carry it through the air. Water can also cause erosion, as waves, rivers, or streams pick up sediment and move it from place to place. Finally, ice can cause erosion; for instance, glaciers carve out valleys by pushing aside rock and sediment.
