Across
- 5. A type of energy that comes to earth from the sun can damage the skin and cause cancer and is mostly absorbed by the ozone layer
- 6. layer of electrically charged particles in the thermosphere that absorbs AM radio waves during the day and reflectsthem back at night
- 9. Air planes travel in this layer the ozone layer is located here
- 10. Earth's air which is made up of a thin layer of glasses solids and liquids forms a protective layer around the planet and is divided into five distinct layers
- 13. thermal energy travelling in waves or rays
- 14. protects earth from gamma and x-ray radiation
- 16. thermal energy going through a material by tough
- 18. Above 80 km and extends to space has the highest temperatures contains the upper portion
Down
- 1. substance heats up and become less dense releases heat cools down and becomes more dense sinks and repeats forming currents
- 2. group of chemical compounds used in refrigerators air conditioners foam packages and aerosol sprays that may enter the atmosphere and destroy ozone
- 3. outermost layer of the atmosphere satellites are located here
- 4. narrow belt of strong winds that blows near the top of the troposphere
- 7. layer of the stratosphere with a high concentration of ozone absorbs most of the suns harmful unltraviolet radiation
- 8. how energy travels from the sun to earth can be helpful or harmful and are reflected absorbed or scattered
- 11. light reflecting off a particle and going in all directions creates blue skies
- 12. shooting stars known as meteors burn up in this layer contains the lower portion of the ionospher
- 15. layer of Earth's atmosphere that is closest to the ground and contains 99 percent of the water vapor and 75 percent of the atmospheric gases where clouds and weather occur
- 17. keep earth warm at night and cool during the day
