Correct answers: prevailing westerlies, jet stream, and fronts.
- Prevailing westerlies: the predominant mid‑latitude winds move air masses across the continental U.S. from west to east.
- Jet stream: upper‑level fast winds steer and accelerate the movement of air masses and weather systems.
- Fronts: boundaries where air masses meet; the advance of one air mass along a front forces movement and displacement of the other.
Prevailing easterlies and trade winds are tropical/polar wind belts and do not generally drive air‑mass movement across the U.S.
