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
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, primarily caused by
"Getting" wind can also mean converting its kinetic energy into mechanical or electrical power: Make Your Own Wind Chime - Super Simple Wind is air in motion
