Chapter 9

A benchmark is an important step in surveying a map area. a measure of how steep the slope is. a permanent marker on the ground that indicates location and elevation. a marker painted on boulders.

a permanent marker on the ground that indicates location and elevation.

Information on the borders of a topographic map includes all except the year the map was made. the map scale. the types of rocks present in the map area. the latitude and longitude of the four corners of the map

the types of rocks present in the map area.

A vertical exaggeration of 1.00 × on a topographic profile means the slope is very steep. there are several overhangs on cliff faces. the vertical scale of the profile is the same as the map scale. the vertical scale of the profile is 100 times that of the map scale.

the vertical scale of the profile is the same as the map scale.

On a map with a scale of 1:48,000, a distance of 1 mile would be represented by how many inches? 1 1.32 4.8 48

1.32

To show topography in a rugged, mountainous area, the most appropriate contour interval would be 5 feet. 10 feet. 20 feet. 100 feet.

100 feet.

To show topography in a flat coastal area, the most appropriate contour interval would be 5 feet. 10 feet. 20 feet. 100 feet.

5 feet.

Two maps have been drafted so that each fills a sheet of 8½ × 11 paper, one at a scale of 1:24,000, and the other at 1:62,500. Which of the following statements correctly describes these maps? The map with the scale of 1:24,000 covers more area than the other. The map with the scale of 1:62,500 covers more area than the other. Both cover the same amount of area. The map with the scale of 1:62,500 can show more details of topography.

The map with the scale of 1:62,500 covers more area than the other.

Contour lines on a topographic map are spaced at equal distances from one another horizontally. cross one another at rivers. are usually brown. cannot be drawn below sea level.

cannot be drawn below sea level.(?)

Small tick marks (hachures) on contour lines indicate steep slopes. gentle slopes. hilltops. depressions.

depressions.

Contour lines on a map connect points spaced equal distances from one another. of equal elevation. of interest to geologists. that mark uphill or downhill trails.

of equal elevation.

The zero contour line is also known as the North Pole. the international date line. the equator. sea level.

sea level.

What does a map scale of 1:24,000 indicate? One inch on the map equals 24,000 inches on the ground. One centimeter on the map equals 24,000 centimeters on the ground. One foot on the map equals 24,000 feet on the ground. All of the possible answers are correct.

All of the possible answers are correct.
