5 Matching Questions

  1. warm front
  2. high
  3. pressure gradient force
  4. Friction
  5. Jet Stream
  1. a an area in which the barometric pressure is greater than that of the surrounding air
  2. b Drives air from areas of higher barometric pressure to areas of lower barometric pressure, causing winds.
  3. c the resistance encountered when one body is moved in contact with another. Slows down the speed of wind when it flows over land
  4. d narrow belt of strong winds that blows near the top of the troposphere across the US
  5. e moving weather front along which a warm air mass slides over a cold air mass, producing stratiform clouds and precipitation

5 Multiple Choice Questions

  1. the weight of the air above an object
  2. a body of air that has about the same temperature and moisture throughout
  3. 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. Air pressure pushing on the mercury in the dish forces the mercury in the tube to be higher.
  4. an instrument used to determine the direction that the wind is blowing
  5. a front where a warm air mass is caught between two colder air masses and brings cool temperatures and large amounts of rain and snow

5 True/False Questions

  1. FrontArea of low pressure where wind will move towards, associated with cloudy and rainy weather and air that is rising

          

  2. LowArea of low pressure where wind will move towards, associated with cloudy and rainy weather and air that is rising

          

  3. lowan area in which the barometric pressure is lower than that of the surrounding air

          

  4. aneroid barometeran instrument that measure air pressure, An instrument that measures changes in air pressure without using a liquid. Changes in the shape of an airtight metal box cause a needle on the barometer dial to move.

          

  5. Convection CurrentThe way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left.
