Of the following physical properties of the atmosphere, which is/are true? Choose all that apply.
-Warm air holds more water vapor than cool air. -Low pressure at the surface is associated with rising air (movement away from the surface). -Air always moves from high-pressure regions toward low-pressure regions. -The air temperature is warmer near Earth's surface than in the upper part of the troposphere.

-between 5 and 30 latitudes -between 30 and 60 latitudes
At what latitude(s) on Earth is the speed of rotation the greatest?
0 degrees
The Trade Winds are one type of prevailing wind pattern. How many other types of prevailing winds are there among earth's global wind patterns?
2
Considering our current technology, how much of the U.S. energy needs could realistically be supplied by renewable wind energy?
20%
The average albedo of Earth's surface is about:
30%
Which of the following will cause the lowest air pressure at the surface?
A column of warm, less dense air
Of the following statements about the tilt of Earth's axis, which one is true? Select only one answer.
An increase in Earth's tilt would cause colder winters and warmer summers.
Why does wind between the equator and 30 degrees south come out of the southeast?
Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect.
The prevailing westerly winds blow in which of the following directions in the Southern Hemisphere?
From northwest to southeast
How are rain patterns different near warm and cold fronts?
Rain near a cold front occurs over a smaller spatial area and is more intense than near a warm front.
Where does rain occur in a cold front?
Rain occurs along and behind a cold front.
Where does rain occur in a warm front?
Rain occurs along and in front of a warm front.
Why does rain occur near a cold front?
Rising warm air cools, resulting in cloud formation and rain.
Why does rain occur near a warm front?
Rising warm air cools, resulting in cloud formation and rain.
What term is used to describe the effect on air movement produced by Earth's rotation?
The coriolis effect
Which of the following statements about the Coriolis effect is correct?
The magnitude of the Coriolis effect depends on how long the object is in motion.
What determines whether a front is called a cold front or a warm front?
The type of front is determined by which air mass is moving.
What is the air that sinks at latitudes of 30 degrees north and south like?
This air is cool and dry.
Why is it colder in winter than in summer?
When the Northern or Southern Hemisphere of Earth is tilted away from the sun it is winter because that part of Earth receives less direct energy from the sun.
In which direction would winds move at the poles if Earth rotated in the opposite direction?
Wind near the north pole would move to the northeast, and the wind near the south pole would move to the southeast.
Which of the following will cause the highest air pressure at the surface?
a column of cool dense air
The percentage of solar radiation reflected from the surface of Earth back into space is known as the __________.
albedo
Earth's polar regions (above 60° latitude) are classified as deserts because __________.
cold, dry sinking air in the polar high regions produces little precipitation
The air in the center of the eye of the hurricane is ________ air moving ________.
cool dry; downward
Idealized pressure belts and wind systems are significantly modified by Earth's tilted axis of rotation and:
differences in the heat capacities of the ocean and land.
Weather (short-term conditions of air temperature, wind speed/direction, precipitation, and atmospheric pressure) occurs because __________.
earths surface is heated unevenly by the sun
The Doldrums occur in which of the following regions?
equatorial (0 to 5 degrees)
What type of force is the Coriolis effect?
fictitious
The trade winds blow in which of the following directions in the Northern Hemisphere?
from northeast to southwest
The trade winds blow in which of the following directions in the Southern Hemisphere?
from southeast to northwest
The prevailing westerly winds blow in which of the following directions in the Northern Hemisphere?
from southwest to northeast
The intensity of solar radiation received at lower latitudes (near the equator) compared to higher latitudes (near the poles) is:
greater
As discussed in the video, air always moves from _____ atmospheric pressure regions to _____ atmospheric pressure regions.
high; low
In coastal regions, sea breezes happen ________ and land breezes happen ________.
in the afternoon; at night
A disorganized array of clouds and thunderstorms with little or no rotation is known as a TROPICAL DISTURBANCE 2. In a TROPICAL DEPRESSION, wind speeds are below 38 miles per hour. 3. If winds are between 38 and 74 miles per hour, the condition is called a TROPICAL STORM. 4. In order to be considered a HURRICANE, wind speeds must be in excess of 74 miles per hour. 5. The storm is given a name once it reaches the TROPICAL STORM stage. 6. Half or more of TROPICAL STORMS(s) eventually become hurricanes.

The strength of a hurricane is ranked from 1 to 5 on the:

the boundary between two air masses of different temperatures
The thickness of sea ice is limited primarily by __________.
