What phenomenon moves air from high-pressure to low-pressure areas due to differences in heating?

• A. Winds
• B. Fronts
• C. Climate
• D. Polar

Answer: (A)

When parts of the atmosphere are heated differently, the air expands and becomes less dense in the warmer areas, creating lower pressure there, while cooler areas become relatively higher pressure. Air always moves from regions of higher pressure to regions of lower pressure in an attempt to balance that difference. This horizontal movement of air is what we call winds. Fronts describe boundaries between different air masses and aren’t the general force behind the movement, climate is about long-term patterns, and polar refers to a region, not a process. So the phenomenon moving air from high-pressure to low-pressure areas due to heating differences is Winds.
