Depending on the size of the range and the local climate, uplift may persist until erosion rates or the strength of the crust limits the average elevation of the range from increasing any more. Mountain stream channels are self-perpetuating; as water gathers into rills and channels, the greater the flow, the . Weathering and Erosion in Desert Environments. The difference between weathering and erosion is based on whether a rock's location has changed: Weathering degrades a rock without moving it, while erosion carries rocks and soil away from their original locations. Sedimentation occurs when eroded material that is being transported by water, settles out of the water column onto the surface, as the water flow slows.
