12. 4- How can water be both a constructive and destructive force in land?
Page 1 Para 6
If material is removed, erosion happens. If material is built up, deposition builds new land.

20. 7- What does the contour interval tell you about the map?
Page 2 Para 11

21. 7- What does the contour interval tell you about the map?
Page 2 Para 11
The contour interval is the distance between any two contour lines. The closer the lines, the steeper it is.

24. 8- How can you tell a mountain is very steep on a topographic map?
Page 2 Para 12
Lines near each other indicate a steep slope while lines further apart are a gentler slope.
