Exam 1 Study Guide || Answers 100% Rated Correct.
Variable gasses in the atmosphere correct answers CO2 , Water Vapor , O3 (ozone) ,
CH4(methane)
Permanent gasses in the atmosphere correct answers Oxygen (O2) , Nitrogen (N2) , Nobel
Gasses
Characteristics of a variable gas correct answers Concentration is changing ; sources and sinks
are not consistent
Characteristics of a permanent gas correct answers Concentration in atmosphere remains
constant ; sources and sinks consistent
Examples of green house gasses correct answers CH4 , CO2 , CFCs , O3
Why are scientists predicting global warming? correct answers The concentration of greenhouse
gasses in the atmosphere has been rising significantly since industrial revolution
What causes the ozone hole? correct answers CFCs (chlorofluorocarbons) ; found in aerosols
What are the implications of ozone depletion? correct answers Decreased absorption of harmful
UV radiation
Density correct answers mass/volume
Pressure correct answers force / area
, What equation relates density, pressure, and temperature correct answers Ideal gas law ; P∝ DT
What is used to measure density, pressure, and temperature? correct answers Weather balloons
How do altimeters work? correct answers Aneroid barometer inside measures pressure and infers
your altitude
Standard lapse rate correct answers Temperature decreases 2°C for every 1000ft up to 36000ft
What causes indicated altitude to differ from the true altitude? correct answers Changes in
surface air pressure, temperature, elevation
What are the four layers of the atmosphere? correct answers troposphere, stratosphere,
mesosphere, thermosphere
What layer does most weather occur in ? correct answers Troposphere
What layer of the atmosphere contains the ozone layer? correct answers Stratosphere
In the troposphere temperature (increases/decreases) with altitude. Why? correct answers
Decreases ; heat comes from ground
In the stratosphere temperature (increases/decreases) with altitude. Why? correct answers
Increases ; absorption of UV radiation by the ozone layer
In the mesosphere temperature (increases/decreases) with altitude. Why? correct answers
Decreases ; fewer molecules to absorb radiation
