Lesson Outline Answer Key for Understanding Erosion and Deposition Processes

Use graded diagrams with arrows to check student understanding of wearing down by water wind ice and gravity. Mark correct responses where material breaks apart during transport and collects as layers near rivers coasts or valleys.

Written solutions should define wearing down as physical or chemical breakdown and placement as settling of particles after motion slows. Credit examples naming streams glaciers waves or wind plus landforms such as deltas dunes or floodplains.

Check math items showing rate links using slope length water speed or particle size. Full credit requires clear cause result links supported by sketches or labeled maps.
