Question

Instrument use to measure atmospheric pressure is ________________

• A. Thermograph
• B. Barometer
• C. Anemometer
• D. Psycrometer

Hint:

Associate these prefix meanings to identify instruments:
- Baro- = Pressure (Barometer)
- Thermo- = Heat/Temperature (Thermograph)
- Anemo- = Wind (Anemometer)
- Psycro- = Cold/Moisture (Psychrometer)

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Meteorological parameters, such as temperature, pressure, wind speed, and humidity, are measured using specialized weather station instruments.

Step 2: Detailed Explanation:
Let us identify the functions of each instrument:
- Barometer (B): This instrument measures atmospheric (air) pressure.
Mercury barometers and aneroid barometers are the most common types.
Changes in atmospheric pressure are used in weather forecasting to predict weather patterns (such as low pressure indicating storms).
- Thermograph (A): This instrument continuously records temperature over time on a chart or digital media.
- Anemometer (C): This instrument measures wind speed and direction.
- Psychrometer (D): A type of hygrometer that uses two thermometers (a dry bulb and a wet bulb) to measure relative humidity and dew point.
Therefore, the correct instrument for measuring atmospheric pressure is the barometer.

Step 3: Final Answer:
The instrument used to measure atmospheric pressure is the barometer.
