  1. Weather
    The condition of Earth‘s atmosphere at a particular time and place.
  2. Atmosphere
    The envelope of gases that surrounds Earth.
  3. Ozone
    A form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
  4. Water Vapor
    Water in the form of a gas.
  5. Density
    The amount of mass of a substance in a given volume.
  6. Pressure
    The amount of force pushing on an area.
  7. Air Pressure
    The pressure caused by the weight of a column of air pushing down on an area.
  8. Barometer
    An instrument used to measure changes in air pressure.
  9. Mercury Barometer
    An instrument that measures changes in air pressure, consisting of a glass tube partially filled with mercury, with its open end resting in a dish of mercury.
  10. Aneroid Barometer
    An instrument that measures changes in air pressure without using a liquid.
  11. Altitude
    Elevation above sea level.
  12. Troposphere
    The lowest layer of Earth’s atmosphere Tropo- means “to turn”
  13. Stratosphere
    The second-lowest layer of Earth’s atmosphere. Strato- means “layered”
  14. Mesosphere
    The layer of Earth’s atmosphere immediately above the stratosphere. Meso- means “middle” or “between”
  15. Thermosphere
    The outermost layer of Earth’s Atmosphere. Includes the Ionosphere and the Exosphere. Thermo- means “heat’; Exo- means “outer.”
  16. Electromagnetic Wave
    Waves that transfer electric and magnetic energy through the vacuum of space.
  17. Radiation
    The direct transfer of energy by electromagnetic waves.
  18. Infrared Radiation
    Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves.
  19. Ultraviolet Radiation
    Electromagnetic waves with wavelengths that are shorter than visible light but longer than x-rays.
  20. Scattering
    Reflection of light in all directions.
  21. Greenhouse Effect
    The process by which heat is trapped in the atmosphere by gases that form a “blanket” around Earth.
  22. Temperature
    A measure of how hot or cold an object is compared to a reference point.
  23. Thermal Energy
    The total energy of motion in the particles of a substance.
  24. Thermometer
    An instrument used to measure temperature.
  25. Heat
    The transfer of thermal energy from one object to another because of a difference in temperature.
  26. Conduction
    The direct transfer of thermal energy from one substance to another that it is touching.
  27. Convection
    The transfer of thermal energy by the movement of a fluid.
  28. Convection Currents
    The circulation of a fluid as it alternately heats up and cools down.
  29. Wind
    The horizontal movement of air from an area of high pressure to an area of lower pressure.
  30. Anemometer
    An instrument used to measure wind speed.
  31. Wind-chill Factor
    A measure of cooling combining temperature and wind speed.
  32. Local Winds
    Winds that blow over short distances.
  33. Sea Breeze
    The flow of cooler air from over an ocean or lake toward land.
  34. Land Breeze
    The flow of air from land to a body of water.
  35. Global Winds
    Winds that blow steadily from specific directions over long distances.
  36. Coriolis Effect
    The change that Earth’s rotation causes in the motion of objects and that explains how winds curve.
  37. Latitude
    The distance in degrees north or south of the equator.
  38. Jet Stream
    Bands of high-speed winds about 10 kilometers above Earth’s surface.
  39. Water Cycle
    The continual movement of water among Earth’s atmosphere, oceans, and land surface through evaporation, condensation, and precipitation.
  40. Evaporation
    The process by which water molecules in liquid water escape into the air as water vapor.
  41. Humidity
    The amount of water vapor in a given volume of air.
  42. Relative Humidity
    The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature.
  43. Psychrometer
    An instrument used to measure relative humidity.
  44. Condensation
    The process by which molecules of water vapor in the air become liquid water.
  45. Dew Point
    The temperature at which condensation begins.
  46. Cirrus
    Wispy, feathery clouds made of ice crystals that form at high levels.
  47. Cumulus
    Fluffy, white clouds, usually with flat bottoms, that look like rounded piles of cotton.
  48. Stratus
    Clouds that form in flat layers and often cover much of the sky.
  49. Precipitation

    Long periods of low precipitation.
  51. Rain Gauge
    An instrument used to measure precipitation.
