Air flows from ___ pressure areas to ___ pressure areas

Air flows from ___ pressure areas to ___ pressure areas

• A. high; low
• B. low; high
• C. equal; equal
• D. low; moderate

Answer: (A)

Air moves from regions of higher pressure toward regions of lower pressure because the pressure gradient force pushes air down the pressure difference. When one area has higher pressure, it effectively "shouts" to neighboring air, driving it toward the lower-pressure region. The bigger the difference, the stronger the push and the faster the airflow. In this statement, air flows from high pressure areas to low pressure areas, which matches that natural tendency. Choosing from low to high would counter the natural push and would require external energy or another force to overcome the gradient. Equal pressure means there’s no driving difference, so there’s no net flow. The “low to moderate” option isn’t a standard way to describe how air moves in response to pressure differences.
