Global Weather Patterns

Which is the best explanation for how air masses move across the United States?

• The prevailing westerlies move air masses from west to east across the United States but may be deflected by the jet stream.

• The trade winds move air masses from west to east across the United States.

• The jet stream moves air masses from the Pacific Ocean across the United States.

• The warm air of the Gulf Stream causes air masses to move from the Atlantic Ocean to the Pacific Ocean.
