Weathering is the slow breakdown of rocks on Earth's surface. It happens while the rocks are ‘in place’. Erosion is the process that removes material from where bedrock has been broken down or weathered. Rock can be weathered biologically, chemically or physically. Rock can be eroded by the wind, rain, or by flowing streams and rivers, oceans, ice flows or gravity. Small changes caused by weathering and erosion can have large impacts over time.
