The Atmosphere

The Air Around You

Gases in the AirWhich 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 ColumnThe 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 BarometerWhat would a low air pressure reading look like?

Inside an Aneroid BarometerAn 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 DensityHow densely packed would the molecules be at the different altitudes?

Air Pressure

Layers of the Atmosphere

Troposphere and StratosphereEarth's weather occurs in the troposphere. The stratosphere contains the ozone layer.

Changing TemperaturesThe graph shows how temperatures in the atmosphere change with altitude.

Layers of the Atmosphere

Layers of the Atmosphere

Mesosphere and ThermosphereThe mesosphere protects Earth’s surface from being hit by most meteoroids. In the thermosphere, the air is thin and you cannot feel heat.

Radiation From the SunEnergy travels to Earth as electromagnetic waves. What are the types of electromagnetic radiation in the diagram?

Energy in Earth’s Atmosphere

Energy in Earth’s Atmosphere

Energy in the AtmosphereSome wavelengths reach Earth’s surface. Other wavelengths are completely or partially absorbed in the atmosphere.

Use the higher percentages below to show a bar graph. Give it a title.

Energy in Earth’s Atmosphere

Energy at Earth’s SurfaceComplete 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 EffectThe greenhouse effect is a natural heat-trapping process. What is the sequence of events that causes it to occur?

Energy in Earth’s Atmosphere

Heat Transfer

Measuring TemperatureDoes 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 occurs when a warm radiator heats a room. What type of heat transfer could keep the paper in the air?

Heat Transfer

Wind Direction and SpeedBased on the direction of the wind vane, which direction would the kite be flying?

Winds

Winds

Heating of Earth’s SurfaceThe 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?

The Coriolis EffectThe Coriolis effect determines the direction of global winds.

Winds

Winds

Global Wind BeltsThe 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.
