Which statement is true regarding the structure of warm and cold air columns?

The warm air column is taller than the cold air column because warm air is less dense than cold air. As a result, warm air can rise higher in the atmosphere. This happens because the molecules in warm air move faster and are spaced further apart, allowing them to rise and expand more than colder, denser air, where the molecules are more closely packed.

The increased vertical extent of the warm column compared to the cold column leads to a greater thickness of warm air from the surface to the top of that layer, which is crucial in understanding weather patterns and phenomena such as convection, cloud formation, and storm development. This principle is foundational in meteorology, as it affects everything from local weather to large-scale climate systems.
