Okie doke. Deforestation definitely does not affect mountain building, so D is out. It does kind of affect climate through not absorbing greenhouse gasses and contributing to global warming, but that’s not exactly the best answer, so B is out. Weathering is things breaking down by long exposure to air and erosion is the braking down of different things like wind, water, and other things. I think erosion is the answer, because soil erosion does happen with deforestation through not having trees being able to hold down the soil, which is really important. The answer is A: erosion.
