Local/Global Wind

What causes wind?

• differences in pressure
• differences in oxygen
• differences in thermosphere
• differences in gravity

Why does warm air rise and cold air sink?

• warm air is warmer
• cold air is colder
• warm air is less dense than cold air
• cold air is less dense than warm air

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

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure
• Wind is the movement of air to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

Where does the initial source of energy come from that creates winds?

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

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.

Which statement correctly describes the properties of cold air?

• less dense and less pressure than warm air
• more dense and more pressure than warm air
• more dense and less pressure than warm air
• less dense and more pressure than warm air

_{Which diagram shows the formation of a land breeze?}

• diagram Y
• diagram X
• neither 
• both

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.

Cool air moving across land and warm air rising up from the ocean will result in:

• land breeze
• sea breeze
• warm breeze
• no breeze
