What information does a wind vane provide?

Answer and explanation

Correct answer: Wind direction

A wind vane is a simple instrument used to find the direction from which wind is blowing. It has a pointer or arrow that can turn freely around a vertical support. When moving air pushes it, the pointer aligns with the wind direction, while a fixed set of compass markings helps the observer read north, south, east, west, or an intermediate direction. It does not measure how hot the air is, how much rain falls, or the pressure of the air.

Therefore option D is correct because it says that a wind vane provides information about wind direction. Option A would require a thermometer, and option B would require a rain gauge. Air pressure is measured with a barometer, not a wind vane. Remembering each instrument with its specific function prevents confusion: vane for direction, thermometer for temperature, rain gauge for rainfall, and barometer for pressure.
