Which force causes air to move from areas of high pressure to low pressure?

The force that causes air to move from areas of high pressure to low pressure is the Pressure Gradient Force. This force arises due to differences in atmospheric pressure. When there is a pressure difference across a distance, the air naturally flows from the region where the pressure is higher to the region where the pressure is lower, effectively seeking to balance the pressure differences in the atmosphere.

This movement is fundamental to wind creation, as the greater the pressure difference, or gradient, the stronger the wind will be. The Pressure Gradient Force is essential in meteorology, as it directly relates to how weather systems develop and evolve. Understanding this force helps explain various weather phenomena, from gentle breezes to strong storms, as air seeks equilibrium in atmospheric pressure.

In contrast, other forces mentioned such as the Coriolis Force, which is related to the rotation of the Earth and affects the direction of wind, and Centrifugal Force, which is more relevant to circular motion, do not directly cause air to move from high to low pressure. Friction Force is important in modifying wind speeds near the surface but does not initiate the movement of air due to pressure differences.
