Question 1
Which statement best describes the amount of solar radiation absorbed by Earth at different locations and times?
Solar radiation is more diffuse and scattered over a large area at the equator.
Solar radiation is affected only by the season of the year.
Solar radiation is highest at the poles because of reflection off of fresh ice and snow.
Solar radiation decreases with distance from the equator.

Question 2
How does solar radiation at the poles vary from solar radiation at the equator?
Sunlight hits Earth nearly vertically at the equator and nearly horizontally at a low angle at the poles.
Sunlight is more diffuse at the equator than at the poles.
Sunlight causes maximum heating at the poles and minimum heating at the equator.
Sunlight heats more units of area at the poles that at the equator.

Question 3
Sunlight must travel through a greater thickness of atmosphere at the equator, making the equatorial regions warmer that other parts of Earth.
True
False

Question 4
If air circulation was due entirely to solar heating, air would rise at the equator and flow non-stop toward the poles until it sank. However, other patterns of global air circulation are observed due to
outside forces produced by ocean currents
the inertial force produced by Earth’s spin on its axis
variations in an area’s proximity to oceans
local variations in topography

Question 5
Suppose you observe that at night, the air just above the ground feels cooler than the air above it. Then, in the middle of a sunny day, you notice that the air close to the ground feels warmer. Which process explains this?
convection
conduction
condensation
greenhouse heating

Question 6
Convection cells in the atmosphere are formed as warm air moves away from the equator and cool air moves away from the poles.
True
False

Question 7
Which of the following statements is true about wind?
Wind flows from areas of high pressure to low pressure.
Wind is most common in the Northern Hemisphere.
Wind only blows from the equator to the poles.
Wind can affect temperature but is not itself influenced by temperature.

Question 8
A low pressure system is formed when an air mass cools over a cool surface and sinks.
True
False

Question 9
Where are the Prevailing Westerlies found?
over the equator
at the poles
between 0 and 30 degrees latitude
between 30 and 60 degrees latitude

Question 10
Which of the following dominates wind movement from zero (0) to 30 degrees latitude in both the north and south?
trade winds
Westerlies
Polar Easterlies
Prevailing Westerlies
