What is the most abundant gas in the atmosphere?
Nitrogen
100
What is one thing humans are doing to increase the greenhouse gasses in the atmosphere?
Burning fossil fuels, deforestation, agricultural activities, etc.
100
Fill in the blank: Relative humidity is ____% at the dew point.
100%
100
Fill in the blank: In the atmosphere as altitude increases, air pressure __________.
decreases
100
What is a large volume of air that has the same characteristics like temperature and humidity called?
Air Mass
200
What is the most distinguishing factor that determines the layers of the atmosphere?
temperature
200
What term describes when air at the surface is colder than the air above it; cold air (and pollutants) are trapped beneath warm air.
temperature inversion
200
What is a measure of the mass of water (grams) in a volume of air?
specific humidity
200
Fill in the blank: Winds blow from areas of ________ to _______ pressure.
high to low
200
What is a boundary between two air masses called?
front
300
What layer of the atmosphere does good ozone exist?
statosphere
300
Where does bad ozone come from and which layer of the atmosphere is it located?
Comes from pollutants from industry, vehicles, households, and power plants; troposphere
300
What is the relationship between air temperature and air capacity?
As temperature increases, capacity increases (air can hold more water).
300
What are lines on a weather map that show equal pressure called?
isobars
300
Draw an occluded front and describe what type of weather occurs at this front?
Strong winds and heavy precipitation
400
What layer of the atmosphere is cold and meteors burn up in?
Mesosphere
400
How does conduction transfer heat in the atmosphere?
Conduction occurs between Earth's surface and the lower part of the atmosphere. (Earth's surface is warm and directly heats the air molecules near it).
400
Fill in the blank: When air cannot hold any more water vapor at a given temperature, it has reached _________.
saturation OR dew point
400
What weather occurs at a low pressure system AND a high pressure system?
low = bad weather; clouds, wind, precipitation
high = good weather; fair, calm, sunny
400
Which front includes two air masses moving in the same direction?
Warm Front
500
List each layer of the atmosphere and how temperature changes with altitude.
Troposphere = decreases; Stratosphere = increases; Mesosphere = decreases; Thermosphere = increases; Exosphere = no significant change
500
Name at least 4 greenhouse gasses in our atmosphere that we discussed.
Carbon Dioxide, Water Vapor, Methane, Nitrous Oxide, CFCs
500
The capacity of a piece of air is 67 g, the relative humidity is 35%. What is the specific humidity?
23.5 g
500
slow wind speeds (isobars are farther), cold front so cooler temperatures, precipitation, rain/thunderstorms
500
What weather is occuring near New Mexico and Colorado and why?
Good, clear, fair weather because of the High Pressure system.
