PHYSICAL SETTING / EARTH SCIENCE - JUNE 2002

PART A

Directions (l-35): For each statement or question, write on the separate answer
sheet the number of the word or expression that, of those given, best completes the statement or answers the question. Some questions may require the use of the Earth Science Reference Tables.

1 The dashed line on the map below shows a ship’s route from Long Island, New York, to Florida. As the ship travels south, the star Polaris appears lower  in the northern sky each night.

The best explanation for this observation is that Polaris

(1) rises and sets at different locations each day
(2) has an elliptical orbit around Earth
(3) is located directly over Earth’s Equator
(4) is located directly over Earth’s North Pole

2 When the dry-bulb temperature is 22°C and the wet-bulb temperature is 13°C, the relative humidity is

(1) 10%      (3) 41%
(2) 33%      (4) 59%

3 As the altitude increases within Earth’s stratosphere, air temperature generally

(1) decreases, only
(2) increases, only
(3) decreases, then increases
(4) increases, then decreases

4 The diagrams below represent four rock samples. Which rock was formed by rapid cooling in a volcanic lava flow? [The diagrams are not to scale.]

5 On June 21, some Earth locations have 24 hours of daylight. These
locations are all between the latitudes of

(1) 0° and 23 1/2 ° N
(2) 23 1/2° N and 47° N
(3) 47° N and 66 1/2° N
(4) 66 1/2° N and 90° N
