This investigation will help you to:

1. Understand that erosion refers to processes in which gravity, moving water, wind, and ice wear away pieces of rock.
2. Test and analyze a model to determine factors that affect the rate of erosion in rivers or shorelines.
3. Discover how some landforms are shaped by erosion.
4. Understand that erosional processes involve the geosphere, the atmosphere, and the hydrosphere.
5. Explore how humans interact with the Earth system as they engineer ways to reduce erosion by water.
