The thin layer of gasses that surrounds Earth
Atmosphere
The ratio of water vapor the air contains to the maximum amount it could have at that temperature
Relative humidity
The force excited by air on the area below it
Air pressure
The lowest layer of the atmosphere the one directly above the ground
Troposphere
The layer of the atmosphere above the troposphere
Stratosphere
Ozone concentrated in a portion of the stratosphere
Ozone layer
The layer of the atmosphere above the stratosphere extends to 50 to 80 km above sea level
Mesosphere
The top layer of the atmosphere extends from 80 km above sea level infinitely into space
Thermosphere
The transfer of energy through space
Radiation
The transfer of heat directly between two objects in contact
Conduction
The transfer of heat in a fluid as warm parts of the fluid rise from the heat source and expand
Convection
Which of the following identifies the layers of the atmosphere incorrect order beginning with the lowest layer
Troposphere stratosphere mesosphere thermosphere
The movement in a fluid as one parts of the fluid rise and cool part sink
Convection current
A large body of air in which property such as temperature pressure and humidity are similar
Air mass
The boundary between air masses that differ in temperature and moisture
Front
Composition of Earth’s atmosphere
78% nitrogen 21% oxygen 1% water vapor
What does it mean to say that the average daytime relative humidity of a particular city is 31%
in general the air contains less than a third of water vapor that it could contain
Explain how a cloud forms
Clouds form when warm moist air rises cools and condenses into tiny droplets or ice crystals these droplets group together to create clouds
What general statement can be made about the relationship between air pressure and altitude
To lower the altitude or height above sea level the higher the air pressure
How does carbon monoxide affect human health?
It interferes with the body’s ability to deliver oxygen
A ____ can trap smog close to the surface. It happens when a layer of cool, dense air stays near the ground and under a layer of warm air
Temperature inversion
Ozone depletion was caused by the fallen chemicals which were used in refrigerators and aerosol cans
Chlorofluorocarbons
In general war American hold less water vapor than cool air
True
The ozone layer is found within the troposphere
False
