frost or ice wedging,  | when water gets into cracks, expands, and cracks the rock |
frost action,  | crumbling rocks by ice and frost |
| erosion | a destructive process which the movement of materials away from one place, gravity is the main force behind this process |
| deposition | the placing of materials away form one place, it is a constructive process where larger pieces of sediment are deposited slowly creating deltas |
plant chemical weathering,  | Fungi and other organisms give off chemicals that change some rocks |
| Glaciers | frozen water that can cause erosion |
chemical weathering,  | the process by which rocks break down due to chemical changes such as ice wedging, carbonic acid, fungi and other organisms |
acid rain,  | precipitation that causes chemical weathering |
water, acid, and air,  | the main culprits in chemical weathering |
