Which way does the pressure gradient force cause air to flow?

The pressure gradient force is a fundamental concept in meteorology that describes how air moves in response to differences in atmospheric pressure. Air flows from areas of higher pressure to areas of lower pressure due to this force. This movement occurs because the air seeks to equalize the pressure differences in the atmosphere.

When there is a pressure difference, the air molecules in the high-pressure area experience a greater force than those in the low-pressure area, which causes them to push towards the area of lower pressure. The larger the difference in pressure, also known as the pressure gradient, the stronger the force driving the air movement. This flow is a crucial factor in weather patterns, wind formation, and the development of various meteorological phenomena.

The other options propose incorrect directions for air movement in relation to pressure differences, making option A the correct choice.
