__________, _____________, and _________________carry away weathered rock or soil to another place. | Rivers, Streams, and Runoff |
_______________________ moving streams and rivers carry big and small rocks downstream. | Fast |
______________________ moving water carries smaller rocks and soil downstream. | Slow |
Moving water can also cause__________________ carrying the soil away to a different location | Soil Erosion |
