Wind is air in motion, primarily caused by the uneven heating of the Earth's surface by the sun. This creates pressure differences where air naturally moves from high-pressure areas to low-pressure areas.
These measure wind speed. You can build a DIY version using paper cups, straws, and a pencil. As the wind blows, the cups spin, and the rotations per minute can be calculated to determine speed. get wind
To understand wind, we must measure its speed and direction using specific instruments: Wind is air in motion, primarily caused by
These determine wind direction. They are often made with a simple arrow design on a rotating axis that points into the wind. Wind is air in motion
