What does a wind vane primarily indicate?

• A. Direction of the Wind
• B. Wind Speed
• C. Humidity Level
• D. Atmospheric Pressure

Answer: (A)

Wind direction is what a wind vane shows. A wind vane is designed to rotate freely and align with the wind, pointing toward the direction from which the wind is coming. This helps us know where the wind originates, which is important for weather forecasting and planning. It doesn’t measure how strong the wind is—that’s what an anemometer does. It also doesn’t measure humidity or atmospheric pressure, which are read with a hygrometer and a barometer, respectively.
