Sample questions

1. Which of the following weather instruments is primarily used to measure atmospheric pressure?

   1. Anemometer
   2. Barometer
   3. Hygrometer
   4. Thermometer
   Show answer

   Answer: B. Barometer

   A barometer is an instrument used to measure atmospheric pressure. An anemometer measures wind speed, a hygrometer measures humidity, and a thermometer measures temperature.

2. What is the term for the measure of the amount of moisture in the air?

   1. Temperature
   2. Pressure
   3. Humidity
   4. Precipitation
   Show answer

   Answer: C. Humidity

   Humidity is the term used to describe the concentration of water vapor in the air. Temperature measures heat, pressure measures the force exerted by the atmosphere, and precipitation is water falling from the atmosphere.

3. Which of the following best describes wind chill?

   1. The actual temperature of the air.
   2. The effect of wind on the perceived temperature, making it feel colder.
   3. The amount of moisture in the air.
   4. The rate at which precipitation falls.
   Show answer

   Answer: B. The effect of wind on the perceived temperature, making it feel colder.

   Wind chill is a measure of how cold the air feels to humans or animals, due to the combined effect of low temperature and wind speed removing heat from exposed skin.

4. On a weather map, a location labeled with a high pressure (H) typically indicates:

   1. Conditions favorable for storms and rain
   2. Generally clear skies and calm weather
   3. Strong westerly winds
   4. Low temperatures
   Show answer

   Answer: B. Generally clear skies and calm weather

   High-pressure systems are associated with sinking air, which inhibits cloud formation and leads to stable, often clear, and calm weather conditions.

5. A period of abnormally hot and dry weather can be classified as a(n):

   1. Cyclone
   2. Flood
   3. Drought
   4. Blizzard
   Show answer

   Answer: C. Drought

   A drought is a prolonged period of abnormally low rainfall, leading to a shortage of water. Heat and dryness are characteristic features.
