Look at your Atmosphere KWL chart. Now that we have studied the atmosphere,
fill in the L on the chart (what you have learned).
Turn in your lab from yesterday if you did not turn it in yesterday.

Atmosphere ( page 134 & 118-125) Layers Composition (%’s of O2 & N2) Air Pressure & how it affects our bodies
Weather Factors (page 135 & 126-137) Heat Transfer (radiation/convection/conduction) Electromagnetic radiation from the sun (IR,
visible, UV) Winds – local (land & sea) and global Clouds – types (cumulus, cirrus, stratus,
cumulonimbus)
What absorbs ultraviolet radiation in the atmosphere?
Ozone
What type of energy heats up the Earth’s atmosphere?
Infrared radiation
What is the greenhouse effect? Process by which gases hold heat in the
atmosphere
What type of heat transfer requires two objects to be touching?
Conduction
How is heat transferred to you from a campfire?
Radiation
What type of heat transfer is responsible for heating the troposphere?
Convection
Why does convection happen?
a. Warm air is more dense than light air
b. Warm and cold air have the same density
c. Cold air is less dense than warm air
d. Cold air is more dense than warm air
Wind is caused by differences in
a. Precipitation
b. Humidity
c. Air pressure
d. Turbulence
What tool do we use to measure wind speed?
Anemometer
How are local winds different from global winds?
Local winds are caused by unequal heating in a small area
Why do land breezes form? Because land cools off faster than water
What type of wind blows from a specific direction over long distances?
Global wind
Earth’s rotation makes winds seem to curve. What is this called?
Coriolis effect
What tool is used to measure relative humidity?
Psychrometer
When do clouds form? When water vapor condenses
What type of clouds produce thunderstorms?
Cumulonimbus
What are high feathery clouds called? Cirrus
What type of clouds are layered and cover most of the sky?
Stratus
Any form of water that falls from a cloud is called what?
Precipitation
How does energy travel through space to the Earth?
As electromagnetic waves
Energy from the sun that reaches the Earth is visible light, infrared radiation and _______________.
Ultraviolet radiation
What tool is used to measure how hot or cold the air is?
Thermometer
A sea breeze is a type of what kind of wind? Local wind
What tool is used to measure air pressure? Barometer
Which heats up more quickly, land or water? Land
What is the most abundant gas in the atmosphere?
Nitrogen
What percent of the atmosphere is oxygen? 21%
What is altitude? The measurement of how high something is
above sea level
What human activity causes the most air pollution?
Vehicle exhaust
What is rain or sleet mixed with acids called?
Acid rain
Why does air have pressure? Because it has mass
How do we measure air pressure? With a barometer
What does the ozone layer do? Protects us from ultraviolet radiation
Photochemical smog forms in the presence of what?
Sunlight
What happens to happens to air pressure as altitude increases?
It decreases
In what layer of the atmosphere is the ozone layer or ozonosphere found?
Stratosphere
What are the four main layers of the atmosphere in order from the ground upwards?
Troposphere, stratosphere, mesosphere, thermosphere
What does the mesosphere do? Causes meteors to burn up before striking
Earth
Where does the aurora borealis form? In the ionosphere
Where does weather occur? The troposphere
