Describing Weather and Weather Patterns Assessment

1. An instrument that measures wind speed is the:

• barometer
• dew point
• anemometer

2. The amount of water vapor in the air is known as:

• rain
• humidity
• dew point

3. This is the temperature at which air is saturated and condensation occurs and small droplets of water form:

• rain
• humidity
• dew point

4. This is an instrument that measures humidity:

• barometer
• anemometer
• psychrometer

5. When water turns from a gas (water vapor) back to a liquid it is called:

• Precipitation
• Condensation
• Evaporation

6. It is a large body of circulating air with high pressure at its center and lower pressure outside the system; brings stable, good weather

• Low pressure system
• High pressure system

7. It is the boundary between two air masses:

• air mass
• weather front
• hurricane
• tornado

8. This is an intense tropical storm with winds exceeding 119 km/hr

• hurricane
• tornado
• blizzard
• thunderstorm

9. Is the measure of average kinetic energy of molecules in the air:

• humidity
• air temperature
• air pressure

10.This forms when a cold mass meets a warm mass but neither have enough force to move the other.

• warm front
• cold front
• stationary front
• occluded front
