100
A measure of how much mass takes up a specific amount of space.
What is density?
100
Air density is greatest in this layer of the Earth's atmosphere.
What is the Troposphere?
100
Air masses that form over land and come from colder climates located closer to the Earth's poles are known as
What are continental polar air masses?
100
Weather represents the ______________ conditions of the Earth's atmosphere.
What is temporary?
100
These models are used to present all parameters discussed when presenting the weather for a region or area.
What are station models?
200
If you want to turn a liquid into a gas, you must apply ____________ to the liquid.
What is heat?
200
This layer contains a gaseous compound known as Ozone which absorbs most of the Sun's long-wave UV radiation.
What is the Stratosphere?
200
Air masses that form over regions of water from Tropical areas closer to the Equator are known as
What are Maritime Tropical air masses?
200
When two different air masses come into contact with one another, a _____________ forms, producing a change in weather of a location.
What is a front?
200
What is 1011.9 mb?
300
This process takes place when you move from a gas to a liquid.
What is condensation?
300
The number of air molecules present in the atmosphere decreases as you move higher in altitude above sea level due to a decrease in the ___________________.
What is force of gravity?
300
Air masses that form over water and come from regions of higher temperatures typically have (higher/lower) pressure?
What is lower pressure?
300
When a cold and warm air mass meet, warm air rises, producing clouds and generally unstable weather. This is due to warm air having the capacity to carry _______________.
What is moisture?
300
What are clouds and precipitation?
400
When molecules of water spread farther apart, increasing in movement and taking up more space, they become a gas through the process of _________________.
What is evaporation?
400
Kinetic Energy of the air molecules decreases in altitude due to a decrease in the ________________ between air molecules.
What is collisions?
400
Different air masses exist because there is _______________ ________________ of the Earth's surface?
What is unequal heating?
400
This temperature is the temperature below which the water vapor in air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates.
What is the dew point?
400
A station model with a very low pressure probably has cloud coverage and ________________.
What is precipitation?
500
The number of molecules is very low in the Thermosphere, yet the temperature in the Thermosphere gradually increases into the Exosphere. This occurs because the Thermosphere is _________________ to the energy from the Sun?
What is closest?
500
This represents the ratio of the pressure of water vapor in the air, with respect to how much water vapor is present what the temperature is.
What is relative humidity?
500
After it has begun raining, the humidity of the air closest to sea level ______________.
What is decreases?
