how does air thicken?
often the air is much thicker at great altitudes, on mountain summits. this occurs when air that strikes one side of the mountain cannot continue on its path and therefore splits into two parts. one part moves upward and one part downward. the part that moves downward becomes a vortex that permanently moves up and down, because it cannot escape upward and repeatedly collides with the air stream. In this way the air becomes thicker.
