The Air Around You
Gases in the Air
Which circle graph shows the correct percentage of gases in the
atmosphere? How should each portion of the graph be labeled? What
would be a good title for the graph?
Air Pressure
Air Column
The weight of the column of air
above you puts pressure on you.
How does pressure from air
molecules keep you from being
crushed?
Air Pressure
Reading a Mercury Barometer
What would a low air pressure reading look like?
Air Pressure
Inside an Aneroid Barometer
An aneroid barometer has an
airtight metal chamber, shown
in red. Which diagram shows
the aneroid barometer under
high pressure and which shows
it under low pressure?
Air Pressure
Effect of Altitude on Pressure and Density
How densely packed would the molecules be at the different altitudes?
Layers of the Atmosphere
Troposphere and
Stratosphere
Earth's weather occurs in the
troposphere. The stratosphere
contains the ozone layer.
Layers of the Atmosphere
Changing Temperatures
The graph shows how temperatures in the atmosphere change with
altitude.
Layers of the Atmosphere
Mesosphere and Thermosphere
The mesosphere protects Earth’s
surface from being hit by most
meteoroids. In the thermosphere,
the air is thin and you cannot feel
heat.
Energy in Earth’s Atmosphere
Radiation From the Sun
Energy travels to Earth as electromagnetic waves. What are the types
of electromagnetic radiation in the diagram?
Energy in Earth’s Atmosphere
Energy in the Atmosphere
Some wavelengths reach Earth’s
surface. Other wavelengths are
completely or partially absorbed in
the atmosphere.
Energy in Earth’s Atmosphere
Use the higher percentages below to show a bar graph. Give it a title.
Energy in Earth’s Atmosphere
Energy at Earth’s
Surface
Complete each sentence
with a word from the
Word Bank to learn what
is happening to the
energy at Earth's surface
and in the lower
atmosphere.
Energy in Earth’s Atmosphere
Greenhouse Effect
The greenhouse effect is a
natural heat-trapping
process. What is the
sequence of events that
causes it to occur?
Heat Transfer
Measuring Temperature
Does the tea in the pot have more or less thermal energy than the tea
in the cup? If you know the degrees of Farenheit, how do you find the
degrees of Celsius?
Heat Transfer
Heat Transfer
Heat transfer occurs when a
warm radiator heats a room.
What type of heat transfer
could keep the paper in the
air?
Winds
Wind Direction
and Speed
Based on the direction of
the wind vane, which
direction would the kite be
flying?
Winds
Heating of Earth’s Surface
The angle of the sun's rays causes temperature differences
at Earth's surface. Which area on Earth receives the most direct light from the
sun, and which areas receive the least?
Winds
The Coriolis Effect
The Coriolis effect determines the direction of global winds.
Winds
Global Wind Belts
The Coriolis effect and other factors combine to produce a pattern of wind belts
and calm areas around Earth. Match the descriptions of the global winds with their
location on the globe.
