For the InstructorThese student materials complement the A Growing Concern Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

- Questions based on erosion figures (PowerPoint 2007 (.pptx) 655kB Aug4 14)
- Based on your work today, how does agriculture threaten the sustainability of soil?(2 pts)
A correct answer will consider how the rate of agricultural soil erosion relates to soil production. (1 pt) It should also consider the spatial coverage of eroding landscapes (1 pt).
- Does what you learned today through exploring the figures of natural and cropland erosion support or conflict with your initial perceptions of erosion?(1 pt)
Your answer should refer to your initial impressions of erosion as we looked at the pictures of agricultural and mountain erosion. Did you think mountains or croplands were more erosive? Is this consistent with what you learned by looking at the figures?
- Reflecting on your comparison between the two erosion figures, what question(s) do you still have?
1 question required, more allowed (1 pt).
