Water erosion occurs when rain or snowmelt displaces the soil or rock on the ground. At Capilano Park in Vancouver, BC, Canada, there is a nice visualization of the effects of water erosion on rock, with a gradation of 15, 25, and 50 years. It displays the long-term effects of water erosion and the difference between 15, 25, and 50 years on the same rock.
