  •  15
  • ____ shows How close molecules are to each other in specific place.
    Density
  •  15
  • This determined the WEIGHT if air in a given place
    Air Pressure

  • Fill in the blank. ____ (cold, hot) air produces High air Pressure (density)
    Cold
  •  15
  • Fill in the blank. ____ (cold, hot) air produces Low air Pressure (Density)
    Hot air
  •  15
  • True or False? Wind happens because high pressure cold winds collide with low pressure high winds
    True
  •  15
  • Hot air means ____ (low, or high) pressure
    Low pressure because the particles are moving faster and take up more space
  •  15
  • Cold air means ____ (low, or high) pressure
    High Pressure because the particles are densely packed and are not moving very fast.
