Across
  1. 4. the sum of all solid and liquid particles suspended in air, many of which are hazardous; examples include dust, pollen, soot, smoke, and liquid droplets.
  2. 13. warming of the Earth's surface and the air above it caused by gasses in the air that trap energy from the sun; the heat-trapping gasses are called greenhouse gasses and the most common are water vapor, carbon dioxide, and methane
  3. 14. temperature increases with altitude, hottest layer (1000+ degrees F).
  4. 15. 50-80 km above the earth’s surface, coldest layer of the atmosphere & temperature decreases with altitude, meteors burn in this layer.
Down
  1. 1. starts at top of troposphere to about 50 km, where most jets fly, an ozone layer is found near the 50km mark. The temperature increases with altitude because ozone absorbs UV rays which warms the air.
  2. 2. (Doppler)- a radar tracking system using the Doppler effect to determine the location and velocity of a storm, clouds, precipitation.
  3. 3. is a shell of electrons and electrically charged atoms and molecules, Aurora Borealis occurs here that is in the lower end of the Thermosphere.
  4. 5. (ultraviolet) rays- invisible rays that come from the sun, can burn skin, and cause skin cancer.
  5. 6. the lowest layer of the atmosphere, extending from the Earth’s surface to 6-10 km high, within which there is a steady drop in temperature with increasing altitude, cloud formation and weather occurs here.
  6. 7. to of the atmosphere, satellites orbit here, the upper end of the Thermosphere, blends into space.
  7. 8. the movement caused within a fluid (like air) by warmer, less dense material to rise, and colder, denser material to sink, resulting in heat transfer.
  8. 9. a form of oxygen, O3; in the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. This is sandwiched between the top of the Stratosphere and the bottom of the Mesosphere.
  9. 10. gradient- The change in pressure measured across a given distance.
  10. 11. a narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth.
  11. 12. pressure the force exerted onto a surface by the weight of the air.
