1.  (C) The "path" of something is the "direction" in which it travels.

2. (A) "This phenomenon" refers to the movement of icebergs "to the right side of the direction in which the wind blew."

16. (A) To "rotate" is to "spin" or "turn" around an axis or central point.

3. (C) All points on the planet travel once around the Earth in a single day. Thus the rotational velocity is the same at different latitudes.

4. (D) The author points out the linear speed of a point on the Earth depends on its distance from the equator.

5. (B) The passage states that an object in the Northern Hemisphere near the equator travels faster than an object further north, where the distance around the Earth is less than at the equator.

6. (B) The second square. The transitional phrase "And conversely" indicates that the sentence contains some information showing an opposite tendency to the previous sentence. This would follow the sentence that mentions an object traveling northward, away from the equator, travels relatively faster. The converse means that it travels relatively more slowly as it travels southward.

7. (D) The passage states that at a depth of about 150 meters water moves in the opposite direction to the surface water.

8. (B) Paragraph 4 gives an explanation of how the Coriolis force changes the direction of water flow.

9. (A) To "deflect" is to "turn" to one side.

10. (D) The information about the movement of icebergs in paragraph 1 and the description of the water deflection in paragraph 4 indicate that it is the Coriolis force that deflects ocean water.

11. (A) The passage mentions how the marine ecosystem is affected by water taking the place of water displaced in the Ekman spiral.

12. (B) (D) (E)

The Coriolis force results from the Earth's rotation and the fact that the linear speed (distance traveled in a given time) of a point on the Earth's surface is slower the further it is from the equator ("Because of the Earth's rotation... ").

This causes an object moving away from (or toward) the equator to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere ("Because of deflection... ").

Ocean currents are deflected at an angle with respect to the prevailing wind because of the Coriolis force. Water at successively deeper levels is further deflected in respect to the layers above it, creating a spiral ("Water at... ").
