Why do fluids move toward low pressure areas?

Fluids move toward low-pressure areas due to the principle of pressure differential, which states that fluids naturally flow from regions of higher pressure to regions of lower pressure in an effort to equalize the pressure across the system. This movement is driven by the force exerted by the pressure difference, allowing the fluid to seek a state of equilibrium. This behavior is fundamental in various natural processes and engineering applications, such as in the movement of air in weather patterns or the flow of liquids in pipes.
