#14 Local and Global Winds

What is the initial source of energy that creates winds?

• the moon
• the sun
• the Earth's surface
• the rotation of the Earth

Which term is best described as the movement of air from land to sea?

• global winds
• sea breeze
• land breeze
• local winds

Land and water absorb and release the sun’s heat in different ways. One result of this is a sea breeze. Which statement is true of sea breezes?

• They originate in the day and blow toward the land.
• They originate in the day and blow toward the water.
• They originate in the evening and blow toward the land.
• They originate in the evening and blow toward the water.

What type of winds blow constantly, predictably, and over long distances?

• land breezes
• mountain breezes
• global winds
• land breezes

Why does warm air rise?

• Warm air is more dense than cooler air.
• Warm air has more pressure than cooler air.
• Warm air is less dense than cooler air.
• Warm air has a higher dew point than cooler air.

The Coriolis effect causes ___________.

• the Earth to rotate on its axis
• continental deflection
• global winds and surface currents to move in a curved path instead of a straight line
• toilets to flush the wrong way in the southern hemisphere

In which direction do prevailing westerlies flow?

• from east to west
• from west to east
• from north to south
• from south to north

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.

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.

What kind of breeze is this & what time of day/night would it form?

• Land breeze - daytime
• Land breeze - nighttime
• Sea breeze - daytime
• Sea breeze - nighttime
