3. 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

700 m/km

The average gradient of the stream is 3.5 m/km because it is calculated by dividing the change in field value (700 meters) by the change in distance (200 kilometers).

Explanation

The average gradient of the stream is 3.5 m/km because it is calculated by dividing the change in field value (700 meters) by the change in distance (200 kilometers).

4. 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 meters.

Explanation

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

6. 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 see that the contour lines around Mill River are closer together on the northeast side compared to the southwest side. This indicates a steeper slope on the northeast side, suggesting that the river generally flows in that direction. Therefore, the correct answer is northeast.

7. 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.

The reference line that passes through both the geographic North Pole and the geographic South Pole is 0° longitude. Longitude lines run from the North Pole to the South Pole and are used to measure east-west positions on the Earth's surface. The line at 0° longitude, also known as the Prime Meridian, is the starting point for measuring longitude and it passes through Greenwich, London. Therefore, it is the reference line that intersects both the North Pole and the South Pole.

8. 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.

Based on the given information, we know that the ship's time is 12 noon when the time at the Prime Meridian is 5 p.m. This means that the ship is ahead of the Prime Meridian in terms of longitude, as it is already noon while it is still morning at the Prime Meridian. Therefore, the ship's longitude must be to the east of the Prime Meridian. The only option that represents an east longitude is 75°E, so that is the correct answer.

Based on the given information, we know that the ship's time is 12 noon when the time at the Prime Meridian is 5 p.m. This means that the ship is ahead of the Prime Meridian in terms of longitude, as it is already noon while it is still morning at the Prime Meridian. Therefore, the ship's longitude must be to the east of the Prime Meridian. The only option that represents an east longitude is 75°E, so that is the correct answer.

9. 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°E, 30°N because the diagram represents the latitude-longitude system, and the coordinates are given as degrees of longitude followed by degrees of latitude. The diagram shows that point A is located 15 degrees east of the prime meridian (E) and 30 degrees north of the equator (N).

Point A is located at 15°E, 30°N because the diagram represents the latitude-longitude system, and the coordinates are given as degrees of longitude followed by degrees of latitude. The diagram shows that point A is located 15 degrees east of the prime meridian (E) and 30 degrees north of the equator (N).
