for a vacation, you and your family fly east to west from boston, massachusetts, to seattle, washington. you notice that your flight back home to boston is shorter than your flight to seattle. which phenomenon causes your flight home to be shorter?\nwind - chill factor\ncoriolis effect\njet stream\nprevailing westerlies
Answer
# Brief Explanations:
Jet - stream is a fast - flowing, narrow air current in the atmosphere. Flights from west to east (returning from Seattle to Boston) are often shorter because they can take advantage of the jet - stream's tailwinds, which increase the ground speed of the aircraft. Wind - chill factor affects how cold it feels, not flight times. The Coriolis effect mainly influences large - scale weather patterns and ocean currents, not directly flight times. Prevailing westerlies are broader wind patterns, and the jet - stream is a more specific and impactful factor for flight durations.

jet stream
