Answer: All of the above!
Explanation:
Water- moves across soil and breaks down pieces of rocks
Wind- can blow materials around, such as rocks or sand. Also it can dry out soil.
Ice- carries broken rocks or soil to different places and can cause glacier erosion.
Gravity- thinking about it, earth is the one place with gravity so if gravity changed it can cause objects to move. Also it determines the shape of the earth because the center has more gravitational pull. This gives it a very round shape.
Organisms- more animals means increase of destruction of plants, which can lead to faster erosion.
Sun- the sun is very important. If the earth didn’t get any sunlight there wouldn’t be any life on the planet itself. Which makes it lack rocks, plants, weather, and the atmosphere.
And by that point it’s just not none of the above.
