TEST Review: Week 21 DCA
Topographic Maps & Continental Drift
1) Draw a topographic map. Show the following.
A. At least 10 contour lines and at least two index contours
B. A road
C. A river/or creek
D. The scale
E. A compass rose
F. A depression
G. A hill or mountain; be sure to show the peak
H. Be sure that the hill/mountain has one steep side and one area with a more gradual slope
I. On the side of bottom of the map, show the contour interval
J. Mark/label the area on the map with the highest elevation.
K. Mark & label the area on the map with the lowest elevation.
L. Mark the area on the map with the steepest slope.
2) Define each of the underlined words in #1
3) Draw a simple topographic map of a single mountain with one steep side (left) and one gradual slope (right). Draw a
transect line through the middle of the hill and then draw a profile of the hill below the topographic map.
4) Draw a simple topographic map of two hills side-by-side (left to right). Draw a transect line through the middle of the
hills and then draw a profile of the hills below the topographic map.
5) Explain how to recognize a creek or streambed on a topographic map. Explain how to know the direction it is flowing
(compared to “uphill”).
6) What is Pangaea?
7) Who came up with the idea of “Continental Drift?”
8) What are the four evidences used to support continental drift? Give an example of each.
9) The puzzle-like fit of the continents is one of the evidences given to explain continental drift (yes, this should be one
of your answers for #8!), but the continents don’t fit together perfectly. Why?
10) What was the “missing explanation” that continental drift failed to offer?
11) Explain Sea Floor Spreading
12) What evidence supports Sea Floor Spreading?
13) Explain how sonar works and what it is used for.
14) Define weathering and erosion.
15) Explain how building a dam across a river will affect weathering and erosion.
16) How does development affect weathering and erosion?
