5 Written Questions

1. an 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.
2. a boundary between two air masses of different density, moisture, or temperature
3. moving weather front along which a warm air mass slides over a cold air mass, producing stratiform clouds and precipitation
4. a line on a weather map that joins points having the same barometric pressure
5. The way Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left.

5 True/False Questions

1. Friction → a boundary between two air masses of different density, moisture, or temperature

   True        False

2. Cold Front → forms when cold air moves under warm air which is less dense and pushes air up

   True        False

3. Low → Area of low pressure where wind will move towards, associated with cloudy and rainy weather and air that is rising

   True        False

4. anemometer → a line on a weather map that joins points having the same barometric pressure

   True        False

5. Mercury Barometer → an 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.

   True        False
