Which instrument indicates wind direction in cardinal points?

• A. Weather Vane
• B. Barometer
• C. Rain Gauge
• D. Telescope

Answer: (A)

Wind direction is shown by an instrument that lines up with the wind and reads off the direction from which the wind is coming, using the four cardinal points. A weather vane sits on a pivot and, when the wind blows, it turns to face into the wind. The base usually has a compass-like dial that shows which cardinal direction the wind is coming from, making it clear whether the wind is from the north, south, east, or west. This is different from a barometer, which measures air pressure; a rain gauge, which collects precipitation; and a telescope, which is used for viewing distant objects. So the weather vane is the instrument that indicates wind direction in cardinal points.
