Winds

What two factors determine the direction in which prevailing winds blow?

• the rotation of the Earth on its axis and the cool air from the poles
• the revolution of the Earth around the sun and the cool air from the poles
• the rotation of the Earth on its axis and the sun’s uneven heating of the earth

Which best describes a characteristic of the jet stream?

• It forms a boundary between a cold air mass and a warm air mass.
• It creates the high winds around the eye of a hurricane.
• It forces the hot air along the equator to rise to areas in North America.

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.
