What term describes the boundary between two air masses of different temperatures?

• A. Front
• B. Frontage
• C. Boundary
• D. Weather

Answer: (A)

A front is the boundary between two air masses of different temperatures. When these air masses meet, they don’t mix easily; the contrasting temperatures cause the air to rise along the boundary, which often leads to cloud formation and precipitation. Fronts help explain why weather can change quickly when air masses collide. Frontage isn’t a meteorological term for this boundary, boundary is too general, and weather describes atmospheric conditions rather than the actual dividing line.
