Wind Lesson

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.
• It causes high pressure air masses to rotate clockwise.

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.

How does the jet stream affect weather conditions around the world?

• The weak wind current of the jet stream redirects weather systems around the world.
• The strong wind current of the jet stream prevents weather systems from moving around the world.
