Atmospheric pressure is caused by:

the weight of the air above.

The primary cause of Earth's seasons is:

tilt of Earth's rotation axis, which causes sun angles and daylight length to vary.

altering the amount of oxygen in the atmosphere

Dust and aerosols in the atmosphere are associated with all of the following EXCEPT:

altering the amount of oxygen in the atmosphere They are associated with: optical phenomena such as red sky at sunset reflection of solar energy condensation and cloud formation

has already created a reduction in ozone-depleting gases in the atmosphere.

Most of the radiation emitted by the earth and its atmosphere is in the category of:

infrared

Heat

is a transfer of energy from areas with high temperatures to those with low temperatures.

The term meteorology:

is the study of the atmosphere and its related weather systems.

he two types of heat recognized by meteorologists are:

latent and sensible heat

The two types of heat recognized by meteorologists are:

latent heat and sensible heat.

The wavelengths emitted by the earth are:

June 21

The longest day of the year in the United States occurs on:

June 21

The energy associated with motion is called:

Kinetic Energy

The level of the atmosphere with the highest temperatures is the:

Mesosphere

This country has the greatest variety of weather in the world.

United States

The process of ________ involves the movement or circulation of a mass or substance

convection

With an increase in altitude, air pressure:

decreases at a decreasing rate

On the average, for every 1 km increase in altitude in the troposphere the air temperature:

drops about 6.5 degrees Celsius.

Objects with higher temperatures:

emit more shortwave radiation than cooler objects do.

Low sun angles result in reduced solar energy because:

energy is spread over a larger area.

fresh snow

Of the following choices, the surface with the HIGHEST albedo is:

fresh snow.

Studies have shown that on average ozone depletion is greatest over this area.

Antarctica

In meteorological terminology, the primary difference between convection and advection is:

Convection represents vertical heat transfer and advection represents horizontal heat transfer.

absorb

The atmosphere is strongly ________ with respect to terrestrial radiation.

absorptive

Scientists believe that a growing amount of this gas in the atmosphere will probably bring about a warming of the lower atmosphere.

carbon dioxide

The atmosphere is highly ________ with respect to solar radiation.

transparent
