Table of Contents The Air Around You Air Pressure Layers of the Atmosphere

1. The Atmosphere Table of Contents The Air Around You Air Pressure Layers of the Atmosphere Energy in Earth’s Atmosphere Heat Transfer Winds

2. 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?

3. 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?

4. Air Pressure Reading a Mercury Barometer What would a low air pressure reading look like?

5. 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?

6. Air Pressure Effect of Altitude on Pressure and Density How densely packed would the molecules be at the different altitudes?

7. Layers of the Atmosphere Troposphere and Stratosphere Earth's weather occurs in the troposphere. The stratosphere contains the ozone layer.

8. Layers of the Atmosphere Changing Temperatures The graph shows how temperatures in the atmosphere change with altitude.

9. 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.

10. 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?

11. 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.

12. Energy in Earth’s Atmosphere Use the higher percentages below to show a bar graph. Give it a title.

13. 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.

14. 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?

15. 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?

16. 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?

17. Winds Wind Direction and Speed Based on the direction of the wind vane, which direction would the kite be flying?

18. 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?

19. Winds The Coriolis Effect The Coriolis effect determines the direction of global winds.

20. 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.
