3. What general direction is the stream flowing?
(1) NW
(3) SW
(2) SE
(4) NE
4.
(1)
(2)
(3)
(4)
How do you know the NE section of the map area is the least steep?
The Vs that cross the stream point upstream.
The contour lines are far apart there.
The contour lines are close together there.
The stream goes form downhill to uphill.
Base your answers to questions 5 through 9 on the Earth Science Reference Tables and the contour map below. Points A through
F represent locations on the map.
5. What is the most likely elevation of the surface of Sunfish Lake?
(1) 151 m (3) 55 m
(2) 140 m (4) 28 m
6. Which statement about hill C is best supported by the map?
(1) Hill C is located approximately 2 km west of Cedar River.
(2) The steepest slope of hill C is on the western side.
(3) Hill C has been shaped by glaciers.
(4) The highest possible elevation of hill C is 179 m.
7. If no elevation values were given, which general rule could be used to establish that Cedar River flows into Sunfish
Lake?
(1) Rivers shown on maps generally flow southward.
(2) Rivers always flow toward large bodies of water.
(3) Contour lines bend upstream when crossing a river.
(4) A large body of water is generally the source of water
for a river.
8. Which location has the same elevation as location D?
(1) A
(3) C
(2) E
(4) F
9. Which diagram best represents the topographic profile from location A to location F?
Base your answers to questions 10 through13 on the Earth Science Reference Tables and the topographic map below. The
topographic map represents elevation contours measured in meters. Four straight lines, AB, CD, EF, and GH, have been drawn for
reference purposes.
10. What could be the elevation of point X?
(1) 819 m (3) 841 m
(2) 826 m (4) 850 m
11. Which profile below most likely represents cross section GH?
12. What is the general direction of flow of Mill Creek?
(1) east to west (3) north to south
(2) west to east (4) south to north
13. Where is it steeper?
1. between G and H
2. between E and F
3. between C and D
4. between A and B
Base your answers to questions 14 through 18on the topographic map below. Letters A through F represent locations on the map.
14. What is the contour interval of this map?
(1) 10 m (3) 100 m
(2) 50 m (4) 150 m
15. Toward which direction does Moody Creek flow
(1) southwest (3) northeast
(2) northwest (4) southeast
16. Which location has the lowest elevation?
(1) A (3) C
(2) E (4) D
17. What is the approximate length of the railroad tracks shown on the map?
(1) 15 km (3) 8 km
(2) 12 km (4) 4 km
18. Which diagram best represents the profile along a straight line from point D to point C?
