Across
  1. 3. for speed miles per hour (mph) or kilometers per hour
  2. 8. weather instrument that measures wind speed. Units = mph or kmph.
  3. 12. the condition of the air around us
  4. 15. An estimation about a future event based on data or experience.
  5. 16. Unit used to describe humidity
  6. 19. to get bigger; to take up more space. Can occur when an object has less pressure on it.
  7. 22. Pressure the force on a surface by the mass of the air above it - pushing in all directions; also called atmospheric pressure.
  8. 24. 4th layer of atmosphere (hottest layer, thin air)
  9. 27. The scientific study of Earth's weather
  10. 29. the layer of a mixture of gases (air) surrounding Earth
  11. 32. weather instrument that measures temperature. Unit used = degrees celsius or fahrenheit.
  12. 34. A person who studies the causes and effects of Earth's weather.
  13. 36. 5th and outermost layer of atmosphere (large, transition to space)
  14. 37. Unit used to describe air pressure
Down
  1. 1. A form of water that falls from the clouds and reaches the ground.
  2. 2. weather instrument that measures humidity. Unit used = %
  3. 4. the measurement of the amount of matter in an object or a substance. Measured in grams (g).
  4. 5. A measure of how hot or cold the air is
  5. 6. Direction N, S, E, W, NE, SE...(cardinal directions)
  6. 7. factors properties of the air that affect weather. (air pressure, temperature, wind direction, wind speed, humidity...)
  7. 9. weather instrument that measures air pressure. Unit = inches of mercury or millibars.
  8. 10. Data used to support claims, based on observation and scientific data.
  9. 11. To predict future events or conditions, such as weather.
  10. 13. air in motion
  11. 14. Gases gases present in the atmosphere with amounts that change depending on environmental conditions. Water Vapor, Carbon Dioxide, Ozone, (and Methane). Known as greenhouse gases.
  12. 17. weather instrument that measures wind direction. Unit used = N, S, E, W, NE, NW (cardinal directions)...Can also use a wind vane.
  13. 18. 1st layer of Earth's atmosphere closest to Earth's surface (where weather takes place)
  14. 20. a continuous force applied to the surface of an object, measured in units per square area; the push (force) when compressed air pushes back.
  15. 21. Anything that has mass and takes up space.
  16. 23. the pull or force between Earth and the matter in an object or substance due to gravity.
  17. 25. 2nd layer of Earth's atmosphere (contains OZONE)
  18. 26. Weather weather that is dangerous and/or causes damage
  19. 28. Gases gases present in the atmosphere with amounts that stay constant. Nitrogen (78%), Oxygen (about 21%), Argon (about 1%).
  20. 30. to push particles closer together
  21. 31. 3rd layer of atmosphere (meteors)
  22. 33. The amount of water vapor in the air
  23. 35. Unit used for describing temperature
