1. Why would water
move faster when the lowland is just soil?
2. Why does water
get a chance to return to the upland to collect more load? (This should
lead to a discussion about the water cycle.)
3. When the plants
threw the load pieces, some landed within the lowland. What might these
represent?
4. How much load
does water have if it moves through just soil?
5. Why would water
move more slowly when plants are present?
6. How much load
does water lose when it moves through an area with a few plants? With
more plants?
