Erosion and Deposition
The student is expected to observe and identify slow changes to Earth's surface caused by weathering, erosion, and deposition from water, wind, and ice.
The students know that Earth consists of useful resources and its surface is constantly changing.
Erosion and Sedimentation: Water Encyclopedia (website) - Learn about the roles of ice, wind and water in the transport and deposition of geological materials.
Erosion and Deposition: NASA/Goddard Space Flight Center Education Programs (website) - Students will: 1) observe and identify agents of erosion and deposition by examining the features formed and the processes that influenced their formation; and 2) construct a model that depicts human impact on the environment.

- Assessment Ideas
- Literature Connections
- Additional Resources
Washed Away: Alabama Learning Exchange (website) - Students learn about and research types of water erosion, and explore its relationship with deposition.
Soil Erosion: Science Netlinks (webpage) - Explore and verify that soil erosion is affected by the soil’s makeup; use plant roots, rocks and the slope of the land as experimental factors.
How Was the Grand Canyon Formed? National Geographic Expeditions (website) - Discover how the Grand Canyon was formed, and how the process of erosion enabled its rock layers to be deposited.
Elaboration Lessons and Extensions
Weathering and Erosion: Illinois State Museum Geology Online (website) - Students complete stations around the classroom to learn about different types of weathering and erosion. (Use Part II, “Erosion Stations.”)
Using a Stream Table to Investigate Erosion Control: Maine Geological Survey (website) - Investigate different methods of controlling water-induced topsoil erosion.
Provide photographs of various landforms (valley, plateau, mesa, plains, river delta, etc.), and have students identify/describe the processes responsible for the formation of each.
Journal Writing: Create a systems diagram showing the processes responsible for the formation of each landform discussed in the activity above. The diagram should include the impact of humans (biosphere connection).
