Climate vs. Weather
1. Which one of the following is incorrect:
Northeast trade winds _____
A) blow towards the equator.
B) originate from subtropical high-pressure belts.
C) blow towards the poles.
D) are found between latitudes 30 ̊N and 30 ̊S.
2. In the Pacific Northwest region minimum temperatures _____
A) Are higher away from the coast.
B) Are higher at higher elevations.
C) Are lower in western areas due to the cool temperatures of the surface ocean waters.
D) Vary between western and eastern areas because of the mountain ranges blocking oceanic and Arctic air masses.
3. The main reason polar regions are cooler (on average) than the equator is that _____.
A) the poles are farther from the sun
B) the polar atmosphere is thinner and contains fewer greenhouse gases
C) the poles are permanently tilted away from the sun
D) sunlight strikes the poles at a lower angle
4. It tends to rain a lot near the equator, while there are often deserts at about 30 degrees of latitude north and south of the equator. Which of the following is the best explanation for this global pattern?
A) Prevailing westerly winds blow clouds towards the equator
B) The action of the Hadley Cell leads to warm air rising and releasing moisture near the equator and dry air descending at about 30 degrees north and south of the equator
C) There tend to be mountains near equator and rain shadows at 30 degrees north and south of the equator
D) Ocean currents bring warm water to equatorial latitudes, allowing for more evaporation, and cool water to 30 degrees north and south of the equator
E) The greenhouse effect causes moisture to precipitate out of the air more readily near the equator than at 30 degrees north and south of the equator
5. The north-south orientation of the Coastal and Cascade Ranges in the Pacific Northwest, coupled with the prevailing westerly winds, helps explain what pattern in regional climate?
A) Areas on the west side of these mountain ranges experience enhanced precipitation.
B) Drier air on the west side of the mountains leads to warmer summer temperatures.
C) Areas west of the mountains experience colder winter temperatures than areas east of the mountains.
D) Air masses pushed by the prevailing winds are stopped by mountain ranges causing increased precipitation on the east side of the mountains.
