Properties of Air
In which type of air (warm or cold) are the gas molecules packed closer together?
What is Cold Air
This layer of the atmosphere contains almost all of the weather on Earth.
What is the Troposphere
What type of front passing through an area would be most likely to cause an increase in temperature?
What is a Warm Front
What is the scientific term for a "fight" between two air masses of differing properties (temp, pressure, etc.)
What is a Front
This is the name of large, flat, almost blanket-like clouds which cover much of the sky
What are Stratus clouds
What is the 2nd most abundant gas which makes up the air on Earth?
What is Oxygen
Which two layers of the atmosphere see a decrease in temperature as their altitude increases?
What is the Troposphere and Mesosphere
Describe the symbol of a warm front
This word is used to describe an air mass which has formed over the ocean or another large body of water.
What is Maritime
Describe the process of condensation
The cooling of water vapor which causes a phase change from a Gas --> Liquid
This type of air is light enough that it rises away from Earth's surface.
What is Warm Air
This layer of the atmosphere has the lowest air density.
What is the Thermosphere
Do fronts always cause storms to form?
Yes!
If an air mass forms between the latitudes of 0o and 30o, what can we infer about it?
It is a Tropical air mass?
This prefix means to rain or storm.
What is "nimbo-"
Warm air can generally hold more water vapor than cold air because...
The warm air temperature hinders condensation from occurring AND there is more space between the molecules
Meteors begin to burn up as they fall through the mesosphere due to what force?
What is Friction
Chilly weather and the formations of potentially severe thunderstorms are a result of this air front.
What is a Cold Front
What do we call a large body of air which has a uniform temperature, humidity, and pressure all throughout itself?
What is an Air Mass
What are the two primary forces which drive the water cycle?
The Sun and Gravity
Describe the motion of air at a low pressure system
Surrounding air is pulled in then pushed upwards. This rising of moist air causes the formation of clouds.
The role of the ozone layer is this.
To absorbs harmful UV radiation from the sun
This type of air front occurs when the warm air and cold air are "evenly matched" and are unable to slide past one another.
What is a Stationary Front
The name of an air mass which is cool and dry would be this.
What is Continental Polar
Which type of high-altitude cloud is thin, hair-like and composed of ice crystals?
What are Cirrus clouds
