The one on the top and right is water erosion, The one on the left is caused from a rock being there for so long is starts to become thinner because of the wind. Now the middle left is a natural basin that looks like water flowed through it so again water erosion. The middle right looks like the rocks and dirt fell off a mountain from being loosened from all the water,wind,humans and others so the kind of erosion is accelerated erosion. the bottom left is strong wind erosion. and the bottom right is a landslide. Hope this helps.
