Which term describes the movement of air from high to low pressure?

The term that describes the movement of air from high to low pressure is wind. Wind is created due to differences in atmospheric pressure; when air at a high-pressure area moves toward a low-pressure area, it generates airflow, which we commonly refer to as wind. This movement is driven by the pressure gradient force, which encourages air to flow from regions of higher pressure where air is denser to areas of lower pressure where air is less dense.

Understanding this concept is crucial in meteorology, as wind patterns play a significant role in weather systems, influencing everything from temperature changes to the development of storms. The other options—convection, conduction, and radiation—describe different processes of heat transfer rather than the movement of air in response to pressure differences.
