Global and local winds review

Land changes temperature more quickly than the ocean. How does this fact create sea breezes?

• Cool air falls over land; warm air falls over the ocean creating convection currents during the day.

• Cool air rises over land; warm air rises over the ocean creating convection currents during the night.

• Cool air rises over land; warm air falls over the ocean creating convection currents during the day.

• Warm air rises over land; cool air falls over ocean creating convection currents during the day.

What kind of breeze is this and when would it form?

• Land breeze - daytime

• Land breeze - nighttime

• Sea breeze - daytime

• Sea breeze - nighttime

Which statement is what we have learned about cold air?

• Warm air rises because it is denser.

• Warm air sinks because it is denser.

• Cold air rises because it is denser.

• Cold air sinks because it is denser.

In which direction does wind blow?

• From North to South.

• From South to North.

• From a high pressure area to a low pressure area.

• From a low pressure area to a high pressure area

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 do differences in air pressure affect the movement of air?

• Air always moves from areas of high pressure to areas of low pressure.

• Air always moves from areas of low altitudes to high altitudes

• Air always moves from areas of low pressure to areas of high pressure.

• Air always moves from east to west.

The apparent curving of air to the right in the Northern Hemisphere is caused by _______ and is called the ______ Effect.

• Earth’s rotation…Doppler

• Earth’s rotation…Coriolis

• Earth’s revolution…Doppler

• Earth’s revolution…Coriolis

What is wind?

• movement of air from areas of low pressure to areas of high pressure

• movement of air to a colder area in the atmosphere.

• movement of air from areas of high pressure to areas of low pressure

• movement of air pushed around and bouncing off Earth’s surface.
