Session 2. Why Does Sedimentation Matter?
Moving water carries and sorts sediment, changes landforms, and creates strata. The sediment becomes the base for soil formation, and it is the material of which flood plains, deltas, and natural levees are built. Through a demonstration of the sedimentation process, students will come to understand the significance of the process and seasonal flooding to agricultural activity in the early river valley civilizations.
Key Questions
- How does the process of sedimentation affect soil fertility?
- Why are some river valleys good sites for human settlement?
