Why do commercial airliners encounter very little turbulence above 25,000 feet? A) Water vapor has mostly disappeared at colder elevations and its effect on weather turbulence.
B) The air is so thin at altitudes above 25,000 feet that turbulence has much less effect.
C) There are no clouds above 25,000 feet.
D) The jet stream produces a much smoother flow of air.
