WCOA Earth Science A: Module 4 Exam Review-part 1

The atmospheric layer closest to the earth's surface is the

• exosphere

• mesosphere

• thermosphere

• troposphere

The atmospheric layer that is farthest from the Earth's surface is the

• troposphere

• exosphere

• thermosphere

• mesosphere

Check the boxes for all answers that are layers of Earth's atmosphere.

• stratosphere

• endosphere

• mesosphere

• metasphere

Check the box for all answers that are reasons why the troposphere is so important to humans.

• It is where weather occurs.

• It is the layer with the most oxygen molecules.

• It is where the ozone layer can be found.

• It is where the International Space Station orbits the Earth.

The gas that makes up the majority of the troposphere is

• oxygen

• carbon dioxide

• nitrogen

• water vapor

The temperature at which air becomes cool enough for water saturation to occur is the

• humidity quotient

• dew point

• water break

• relative humidity

A percentage value that conveys the amount of water vapor actually in the air divided by the amount of water vapor that the air can hold at saturation is called

• relative humidity

• absolute humidity

• dew point

• mugginess factor

Alto-cumulus clouds belong in which level of the atmosphere?

• low level

• mid-level

• high level

• very high level

Which cloud is found ahead of the cold front but behind the warm front and are often associated with sever weather?

• stratus

• cumulonimbus

• cirrus

• cumulus

Stratus clouds are

• low-level, flat, hazy, featureless clouds. They do not have texture but look more like a thick haze of fog.

• mid-level, little circular puffs in the sky.

• high level, thin, wispy clouds that form high in the earth’s atmosphere, usually above 18,000 feet.

• low level, puffy cottonballs that generally produce very little precipitation.
