Question

Quizplus · Accepted Answer

When the air warms, it expands and becomes less dense, making it more buoyant and likely to rise. When water vapor content increases, it displaces some of the dry air molecules, causing the air to become less dense and rise. When atmospheric pressure decreases, the air is less compressed and becomes less dense, which also makes it more buoyant and likely to rise. Therefore, all of these options are correct.
