Which of the following can show the direction of the wind?a)An anemome...
To determine wind direction, a wind vane spins and points in the direction from which the wind is coming and generally has two parts, or ends: one that is usually shaped like an arrow and turns into the wind and one end that is wider so that it catches the breeze.

Understanding Wind Direction
Wind direction is a crucial aspect of meteorology, indicating where the wind originates. Among the options provided, the windvane is specifically designed for this purpose.
What is a Windvane?
- A windvane, also known as a weather vane, is a simple instrument that shows the direction of the wind.
- It typically consists of a rotating arm or arrow mounted on a vertical shaft that spins freely to align with the wind.
How it Works
- The wind catches the larger surface area of the arrow, causing it to rotate.
- The pointed end of the arrow points towards the direction from which the wind is blowing (e.g., if the wind is coming from the north, the arrow will point north).
Other Instruments Explained
- Anemometer: Measures wind speed, not direction. It often has cups that spin with the wind, indicating how fast it is blowing.
- Wind Mill: Primarily used for generating energy or pumping water. While it can move with the wind, it does not provide a direct reading of wind direction.
- Barometer: Measures atmospheric pressure and helps predict weather changes, but does not indicate wind direction.
Conclusion
In summary, the correct answer is option 'C' - a windvane, as it is specifically designed to show the direction of the wind, unlike the other instruments which serve different purposes. Understanding these tools helps us better comprehend weather patterns and conditions.
