100
The process where liquid water turns into water vapor and rises into the air
What is evaporation?
100
The layer above the troposphere that contains the ozone layer
What is the stratosphere?
100
The two main properties that describe an air mass (they are based on where the air mass forms).
What are temperature and moisture (humidity level)?
100
The name for the boundary where two different air masses meet

What is (the symbol for) a stationary front?
200
The term for water vapor cooling and changing back into liquid droplets forming clouds.
What is condensation?
200
The last atmospheric layer before outer space where many satellites orbit.
What is the thermosphere?
200
The type of air mass that forms over land in cold regions and brings cool dry weather.
What is continental polar?
200
The front that occurs when a warm air mass slides up over a cooler air mass, often bringing steady rain or clouds.
What is a warm front?
200
Maritime polar air masses may bring these types of precipitation.
What are rain or snow?
300
The process plants use to release water vapor from their leaves into the atmosphere
What is transpiration?
300
Air pressure decreases as altitude does what?
What is increases?
300
The type of air mass that would bring warm, moist air if it formed over oceans near the equator?
What is maritime tropical?
300
This type of front brings sudden storms and a sharp temperature drop when cold air pushes under warm air.
What is a cold front?
300
A stationary front may bring many days of this type of weather.
What is clouds and precipitation?
400
This part of the water cycle restores water to rivers and oceans.
What is runoff?
400
The atmosphere is mostly made up of two gases: 78% Nitrogen and 21% of this gas.
What is oxygen?
400
This area feels hot and dry because of a certain type of air mass overhead.
What is continental tropical?
400
The kind of front is present when neither a cold nor warm air mass is strong enough to replace the other (often causing many days of cloudy weather).
What is a stationary front?
400
Air masses are constantly on the move because of 2 major causes. They are...
What are prevailing westerlies and the jet stream?
500
The process in the water cycle that involves animals exhaling gases and producing water vapor.
What is respiration?
500
Recite the 4 layers of the atmosphere in order starting with the layer closest to Earth's surface.
What are the troposphere, stratosphere, mesosphere and thermosphere?
500
Global winds occur due to uneven heating over large areas which form this.
What are convection currents?
500
A front with two cold air masses and a warm air mass.
What is an occluded front?
500
Warm air gets pushed up above cool air because it is this.
What is less dense?
