2. Words to Know – Section 1 Earth’s Atmosphere
troposphere
ionosphere
ozone layer
ultraviolet radiation
chloroflourocarbon

3. Earth’s air, which is made up of a thin layer of gasses, solids and liquids; forms a protective layer around the planet and is divided into five distinct layers.
atmosphere

4. Layer of Earth’s atmosphere that is closest to the ground, contains 99% of the water vapor and 75% of the atmospheric gases, and is where clouds and weather occur.
troposphere

5. Layer of electrically charged particles in the thermosphere that absorbs AM radio waves during the day and reflects them back at night.
ionosphere

6. Layer of the stratosphere with a high concentration of ozone; absorbs most of the Sun’s harmful ultraviolet radiation.
ozone layer

7. ultraviolet radiation
A type of energy that comes to Earth from the Sun, can damage skin and cause cancer, and is mostly absorbed by the ozone layer.
ultraviolet radiation

8. Group of chemical compounds used in refrigerators air conditioners, foam packaging and aerosols sprays that may enter the atmosphere and destroy ozone.
chloroflourocarbons

9. Words to Know – Section 2 Energy Transfer in the Atmosphere
radiation
conduction
convection
Hydrosphere
condensation

10. Energy transferred by waves or rays.
radiation

11. Transfer of energy that occurs when molecules bump into each other.
conduction

12. Transfer of heat by the flow of material.
convection

13. All the waters of Earth
hydroshere

14. Process in which water vapor changes to a liquid.
condensation

15. Words to Know – Section 3 Air Movement
Coriolis effect
jet stream
sea breeze
land breeze

16. Causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to earth’s rotation.
Coriolis effect

17. Narrow belt of strong winds that blows near the top of the troposphere
jet stream

18. Movement of air from sea to land during the day when cooler air from above the water moves over the land, forcing the heated, less dense air above the land to rise.
sea breeze

19. Movement of air from land to sea at night, created when cooler, denser air from the land forces up warmer air over the sea.
land breeze
