1. Airport
2. River
3. School
4. Contour lines showing a depression
5. Railroad tracks
6. Contour lines showing an elevation
7. Index contour lines are every fifth contour
line and are darker and heavier than others.
8. 1 centimeter equals 0.24 kilometer, or 1 inch
equals 2,000 feet.
9. It cannot because a contour line connects
points of equal elevation.
10. Within the coastline of the island, you
would have eight closed contour lines, one
inside the other, forming a closed loop at the
center.
11. The person could use it to judge the steepness of the land. Experienced skiers and hikers
would want steeper land; less experienced
people would want gentle slopes.
12. contour interval 13. Index contours
14. contour line
15. topographic
What You KY
1. Some maps show where mountains and
plains are.
2. I\ my people us,.i maps to plot a trip or
hi Le in unfamiliT areas.
What You Learned
1.Mapniakers use contour lines to represent
elevatiun, relief, and slope on topographic
map,
2. A map's scale and symbols will help
interpret the map, contour lines.
3. Topographic maps have many uses in
science and engineering, business,
government, and everyday life.
1. topographic
2. a. Elevation b. Relief c. Slope
3. index contour
4. true
5. false
6. a
7,c
8. a. Connects points of equal elevation b.
Change in elevation from contour line to contour line c. Labeled with the elevation in round,
units d. Contour line e. Index contour
9. A large-scale 'nap is one that shows a dosel
up view of part ot Earth's surface.
10. slope
11. They indicate a ridge line when they point
downhill. They indicate a valley when they
point uphill.
12. a. gentle slope b. hilltop c. depression d.
steep slope
13. Businesses use topographic maps to help
decide where to build new stores, housing, or
factories. Local governments use them to build
new schools and other public buildings.
14. You might use one to see whether your trip
would be flat or hilly.
Topographic Maps
Enrich
A
1. You would run several contour lines
together.
2. As seen from above, there is more land
between different elevations on a gentle slope
than on a steep slope. Since contour lines are
drawn as seen from above, widely spacing the
lines for a gentle slope appropriately reflects
Earth's surface.
3. Contour lines connect points of equal elevation. Thus, crossing lines makes no sense.
4. A topographic map of a wilderness area
would probably be easier to read because it
would not be cluttered with symbols for
human-made features.
5. NjSiDS Vs.ill v ary. Sti,a_erit:-, should include as
many variations as thy car, in tb,iir maps.
