Chapter 6 test
The large atmospheric circulation cells that occur between the equator and 30° latitude in each hemisphere are called Hadley cells.
True
Tropical cyclones derive their energy from the water's high latent heat of fusion.
True
Warm air can hold more water vapor than cold air.
True
A cold air mass moving into an area occupied by relatively warm air is called a/an:
cold front.
The lowermost portion of the atmosphere where most weather occurs is called the:
troposphere
Westerlies
prevailing wind pattern at temperate latitudes
Polar easterlies
prevailing wind pattern at polar latitudes
All of the following are true of the movement of Earth's atmosphere except:
warm air is less dense than cool air so it tends to sink toward the Earth's surface.
Near the poles, more energy is reflected back into space than is absorbed.
True
The Coriolis effect describes how moving objects on Earth appear to follow curved paths due to Earth's rotation.
True
A tropical maritime air mass is likely to be:
wet and warm.
The strength of a hurricane is ranked from 1 to 5 on the:
Saffir-Simpson Scale
Inter-tropical Convergence Zone
area where warm, moist air rises close to the equator
A. continent B. sea ice C. iceberg D. ice floes E. ice shelf
continent
The intensity of solar radiation received at lower latitudes (near the equator) compared to higher latitudes (near the poles) is:
greater
Tropic of Cancer
located at 23.5° N latitude
The two most abundant components of dry air are:
nitrogen and oxygen.
Trade winds
prevailing wind pattern at tropical latitudes
The largest loss of life from a hurricane is usually due to:
storm surge.
Air warmed by the land that rises and is replaced by cooler air from the ocean may produce a:
sea breeze.
A hurricane is a very strong high-pressure system.
False
A wedge shaped boundary between two air masses with different densities is typical for a cold front.
False
An iceberg is a variety of sea ice.
False
Coriolis deflection is highest at the equator (0o latitude).
False
The autumnal equinox occurs when the sun is directly overhead along the equator in March.
False
A. nitrogen B. albedo C. oxygen D. troposphere E. water vapor
albedo
Winds blowing out of the north toward the south in the southern hemisphere will appear to:
be deflected toward the east.
Low-pressure regions in the northern hemisphere rotate:
counterclockwise
A. doldrums B. northeast trade winds C. polar easterlies D. southeast trade winds E. westerlies
doldrums
A. maximum sustained winds B. minimum central pressure C. sea surface salinity D. storm surge E. storm diameter
sea surface salinity
The two factors that are most important in determining the density of air are:
temperature and water vapor content.
A. ecliptic B. vernal equinox C. autumnal equinox D. westerlies E. summer Solstice
