Across
  1. 6. Global air circulation patterns within the atmosphere held to Earth by gravity and warmed as heat radiates from Earth; influenced by convection of warm less dense air (rises and spreads out) and cold dense air (sinks).
  2. 7. Amount of water vapor or moisture content in air.
  3. 9. The day-to-day state of the atmosphere.
  4. 10. A body of air extending over a large area (1,000 miles or more) that develops and retains specific characteristics of pressure, temperature, and humidity.
Down
  1. 1. An air mass with greater atmospheric pressure than the surrounding air masses; air moves away from the high pressure, traveling in a clockwise direction.
  2. 2. Forms at the surface of Earth when a warm, moist air mass overtakes a cool, dense, and dryer air mass.
  3. 3. An instrument that measures the amount of atmospheric pressure.
  4. 4. Forms at the surface of Earth when a cold, dry air mass overtakes a warmer, humid air mass.
  5. 5. A map or chart that shows the weather conditions at a specific point in time over a specific region.
  6. 8. An air mass with less atmospheric pressure than the surrounding air masses; air moves toward the low pressure, traveling in a counter-clockwise direction.
