1. Depression contours are used to show craters of a volcano.
2. A map scale of “1 inch equals 2000 feet” is a verbal scale.
3. The Northern and Southern Hemispheres are divided by the equator.
4. 180 Degrees of latitude separate the North and South Poles.
5. A map scale 1:24 000 is a ratio scale.
6. Starting at sea level, seven contour lines (with a contour interval of 20
feet) would be needed to show an island 125 ft high on a map.
7. To determine the average slope of two points on a topographic map,
you need to know the distance between the points and change in
elevation.
8. 180 is the greatest number of degrees that a traveler can ever be from
the prime meridian.
9. The Prime Meridian divides the Eastern and Western Hemispheres.
10. A cliff is the landform shown by many contour lines drawn very
close together.
11.When a contour line crosses a river, the contour lines make a V, or
bends, to form a point in the direction of the river’s source.

12. Latitude indicates locations north and south of the equator.
13.The height above sea level is elevation.
14.A map projection is a system for drawing maps.
15.Short straight lines that indicate depressions are called hachures.
16. Meridians are lines of longitude.
17.0 longitude is called the Prime Meridian
18.A minute is 1/60 of a degree.
19.The difference in elevation between two contour lines is called
contour interval
20.0 latitude represents the equator-.
21. Locations east or west of the prime meridian represent longitude.
22. Parallels are lines of latitude.
23.The International Date Line is 180 longitude.
24. A Map Scale represents the distance along ground.
25. Degrees are units to measure latitude and longitude.
26.An exact elevation indicator is a Benchmark
27.A topographic map is a map showing relief features.
There will be questions on plotting latitude and longitude on a map and there
will be SOL questions that you should be able to answer based on your
understanding the material.
Match the profiles with the correct contour map
