Atmosphere

2. Thermal energy going through a material by touch
5. Outermost layer of the atmosphere, satellites are located here
7. Air planes travel in this layer, the ozone layer is located here
8. Shooting stars known as meteors burn up in this layer. Contains the lower portion. of the ionosphere
9. Thermal energy traveling in waves or rays
14. Layer, Layer of the stratosphere with a high concentration of ozone; absorbs most of the sun's harmful ultraviolet radiation
15. Stream, Narrow belt of strong winds that blows near the top of the troposphere
17. Light reflecting off a particle and going in all directions; creates blue skies
18. Waves, How energy travels from the sun to Earth, can be helpful or harmful, and are waves reflected, absorbed or scattered

1. Radiation, Energy that comes to Earth from the Sun, can damage skin and cause cancer and is mostly absorbed by the ozone layer
3. Layer of electrically charged particles in the thermosphere that absorbs AM radio waves during the day and reflects them back at night
4. Keep Earth warm at night and cool during the day
6. Above 80 km and extends to space, has the highest temperatures. Contains the upper portion of the ionosphere
10. 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
11. Group of chemical compounds used in refrigerators, air conditioners, foam pack- ages, and aerosol sprays that may enter the atmosphere and destroy ozone
12. Substance heats up and become less dense, releases heat, cools down and becomes more dense, sinks, and repeats forming currents
13. Earth's air, which is made up of a thin layer of gases, solids, and liquids; forms a protective layer around the planet and is divided into five distinct layers
16. Protects Earth from gamma and x-ray radiation
