The largest loss of life from a hurricane is usually due to:

storm surge.

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

Saffir-Simpson Scale

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

The large atmospheric circulation cells that occur between the equator and 30* latitude in each hemisphere are called Hadley cells

True

Warm air can hold more water vapor than cold air.

True

nitrogen albedo oxygen troposphere water vapor

albedo

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 (0* latitude).

False

The autumnal equinox occurs when the sun is directly overhead along the equator in March.

False

Tropical cyclones derive their energy from the water's high latent heat of fusion.

False

Inter-tropical Convergence Zone

area where warm, moist air rises close to the equator

Westerlies

area where warm, moist air rises close to the equator

Winds blowing out of the north toward the south in the southern hemisphere will appear to:

be deflected toward the east.

A cold air mass moving into an area occupied by relatively warm air is called a/an:

cold front.

Low-pressure regions in the northern hemisphere rotate:

counterclockwise.

doldrums northeast trade winds polar easterlies Southeast trade winds westerlies

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.

The two factors that are most important in determining the density of air are:

temperature and ozone

The lowermost portion of the atmosphere where most weather occurs is called the:

troposphere

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.

ecliptic vernal equinox autumnal equinox westerlies summer solstice

westerlies

A tropical maritime air mass is likely to be:

wet and warm.
