Rivers top the list of causes of erosion over time. Scholars experiment with wind, water, and ice reshaping sand. They connect the simulations facts about erosion and deposition to understand unique landforms such as the Grand Canyon and...

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

Take a field trip to a location where water and land meet to study patterns of sediment organization in wet habitats: river or ocean beaches, sand dunes, tidal marshes, the edge of a pond, or a woodland stream. Small groups collect pairs...
