Physical Geography Laboratory Exam 1 Study Guide

On a map with a scale of 1:24,000, a measured distance of 1 inch represents an actual distance of:

• 2,000 feet

• 2,300 feet

• 2,001 feet

• 2,100 feet

On a map with a scale of 1:62,500, a measured distance of 4.5 inches represents an actual distance of:

• 4.5 miles

• 4.3 miles

• 4.44 miles

• 5.34 miles

On a map with a scale of 1:250,000, a measured distance of 4.5 inches represents an actual distance of:

• 17.9 miles

• 17.10 miles

• 17.50 miles

• 17.76 miles

On a map with a scale of 1:50,000, a measured distance of 7.5 centimeters represents an actual distance of:

• 3.46 kilometers

• 3.75 kilometers

• 3.90 kilometers

• 3.33 kilometers

Why isn't "0" at the left of the scale?

• Because the number on the left represent negative numbers.

• No, the graphic scale grows (gets enlarged) at a different rate as the map.

• Because the numbers on the left makes it easier to read fractions off the distances represented by the scale.

• Yes

If a map with these graphic scales is enlarged along with the scales (such as by using a photocopy machine):

(a) Will the fractional scale of the map change? Why?

• No, the numbers on the left represent negative numbers.

• Yes, the fractional scale will change because it grows (gets enlarged) while the map does not.

• Yes, the numbers on the left represent negative numbers.

• No, the fractional scale will not change because it grows (gets enlarged) and shrinks with the map itself.

If a map with these graphic scales is enlarged along with the scales (such as by using a photocopy machine):

(b) Will the graphic scale (as shown) still be usable? Why?

• Yes, the graphic scale grows (gets enlarged) at the same role as the map.

• Yes, the fractional scale will change because it grows (gets enlarged) while the map does not.

• No, the graphic scale grows (gets enlarged) at a different rate as the map.

• No, the fractional scale will not change because it grows (gets enlarged) and shrinks with the map itself.

Compare the Mercator projection (Figure 5-1a) to a globe.

(a) Are all of the lines of latitude parallel to each other on both the globe and the Mercator projection?

• Yes

• No, a scale is not always accurate

• No

• Yes, a scale is always accurate

(b) Do all of the parallels and meridians cross each other at right angles on both the globe and the Mercator? (Hint: Look carefully at just the immediate intersection of a parallel and a meridian on the globe.)

• Yes, the distance never changes on a map

• No

• Yes

• No, the distance never changes on a map

(c) On a globe, the meridians converge toward the poles. Describe the pattern of meridians on the Mercator.

• Meridians converge toward the poles

• Meridians do not converge - they go straight up and down on the map

• The meridians in the Eckert Projection go straight up toward the North Pole

• Meridians do not converge - they run left and right on the map
