What is weather?

• Atmospheric conditions of a large area for long periods of time

• Atmospheric conditions of a specific place at a specific time

• Atmospheric conditions of a specific time about a continent

• Something in the sky

Air moves from ______________ pressure to _______________________ pressure. (write your answer as a word, word)

What causes wind?

• Difference in pressure

• Movement of the earth

• Difference in humidity

• Difference in Dew point

What does humidity measure?

• The temperature of the air

• The density of the air

• The amount of water vapor in the air

• The amount of humans in the air

When we measure humidity we write it as a percent. If humidity is 50% what do we know about the amount of water in the air?

• The air is saturated

• The air is half full of water

• The air is completely full of water

• There is no water in the air at all

True or False: Cold air is denser than warm air.

• True

• False

Why does wind seem to curve when it blows across the earth?

• Coriolis Effect: The earth is spinning

• Coriolis Effect: The wind just curves on its own because of pressure

• Coriolis Effect: The humidity of the air causes the wind to change directions

What is air pressure?

• The weight of the air pushing down

• The amount of water vapor in the air

• The amount of energy in the air molecules

• The space that the air takes up

What is it called when air reaches 100% humidity?

• The air is drowning

• The air is at total pressure

• The air has high kinetic energy

• The air is saturated

What happens when air becomes saturated?

• The water vapor in the air condenses back into a liquid

• The water in the air freezes

• The water in the air disappears

• The water vapor in the air becomes really hot
