3. Base your answer to this question on the topographic map below. Points X, Y, and Z are locatons on the map. Elevations are expressed in meters.

What is the elevation of point Z? (Standard 2.1q)?

190 m

220 m

240 m

250 m

300 m

Based on the topographic map, point Z is located at an elevation of 220 m.

Explanation

Based on the topographic map, point Z is located at an elevation of 220 m.

4. Which reference line passes through both the geographic North Pole and the geographic South Pole? (Standard 1.1c).

0° latitude

0° longitude

Tropic of Cancer (23.5°N)

Tropic of Capricorn (23.5°S)

No reference line passes through both poles.

0° longitude is the correct answer because longitude lines, also known as meridians, run from the North Pole to the South Pole and are used to measure east-west positions on the Earth's surface. The prime meridian, which is designated as 0° longitude, passes through both the geographic North Pole and the geographic South Pole. Therefore, it is the reference line that passes through both poles.

0° longitude is the correct answer because longitude lines, also known as meridians, run from the North Pole to the South Pole and are used to measure east-west positions on the Earth's surface.

5. A stream has a source at an elevation of 1000 meters. It ends in a lake that has an elevation of 300 meters. If the lake is 200 kilometers away from the source, what is the average gradient of the stream? (Standard 2.1q) Gradient = Change in Field Value ÷ Change in Distance

1.5 m/km

3.5 m/km

10 m/km

15 m/km

1500 m/km

The average gradient of the stream can be calculated by finding the change in elevation divided by the change in distance. In this case, the change in elevation is 1000 meters (from the source at 1000 meters to the lake at 300 meters) and the change in distance is 200 kilometers. Dividing the change in elevation (1000 meters) by the change in distance (200 kilometers) gives us a gradient of 5 meters per kilometer. Therefore, the correct answer is 3.5 m/km.

The average gradient of the stream can be calculated by finding the change in elevation divided by the change in distance. In this case, the change in elevation is 1000 meters (from the source at 1000 meters to the lake at 300 meters) and the change in distance is 200 kilometers. Dividing the change in elevation (1000 meters) by the change in distance (200 kilometers) gives us a gradient of 5 meters per kilometer. Therefore, the correct answer is 3.5 m/km.

6. The diagram below represents part of Earth’s latitude-
longitude system. What is the latitude and longitude of point A? (Standard 1.1c)

15°E , 30°N

15°S, 30°E

15°W, 30°S

15°N, 30°W

15°S, 30°W

Point A is located at 15° south latitude and 30° east longitude.

Explanation

Point A is located at 15° south latitude and 30° east longitude.

7. Base your answer to this question on the topographic map below. Points X, Y, and Z are locations on the map. Elevations are expressed in meters.

Mill River generally flows toward the (Standard 2.1q):

Southeast

Southwest

Northeast

Northwest

True west

Based on the topographic map, we can observe that the contour lines are closer together on the northwest side of the river and gradually spread apart towards the southeast. This indicates that the elevation is higher on the northwest side and lower on the southeast side. Since rivers generally flow from higher elevations to lower elevations, we can conclude that Mill River generally flows northeast, as it follows the downward slope of the land from the higher elevations in the northwest to the lower elevations in the southeast.

10. When the time of day for a certain ship at sea is 12 noon, the time of day at the Prime Meridian (0° longitude) is 5 p.m. What is the ship’s longitude? (Standard 1.1.d)

75°E

75°W

45°E

45°W

There is not enough information to answer this question.

The time difference between the ship's location and the Prime Meridian is 5 hours. Since each hour of time difference corresponds to 15 degrees of longitude, the ship's longitude can be calculated by multiplying the time difference by 15. Therefore, 5 hours x 15 degrees = 75°E.
