• hottest layer

• airplanes fly here

• closest to the Earth

• ozone layer

• meteors burn up

• coldest layer

• satallites orbit here

• weather formed

What does ozone do?

• reflects UV radiation

• absorbs UV radiation

• allows UV radiation to reach the Earth

• absorbs X-rays

Select the true statements:

• warm air sinks

• warm air rises

• cold air sinks

• cold air rises

What happens when the amount of ozone decreases?

• more UV radiation reaches Earth's surface

• less sunlight reaches Earth's surface

• trees can't get enough sunlight

• CFCs become illegal

How do CFCs affect the ozone layer?

• they increase the amount of ozone

• they block sunlight from reaching the ozone layer

• they cause holes in the ozone layer

• they do not affect the ozone layer

Select the true statements:

• air density increases with altitude

• air density decreases with altitude

• there is less pressure in the atmosphere as you go up

• there is more pressure in the atmosphere as you go up

How do ocean currents affect climate?

• Ocean currents create hurricanes

• Ocean currents stop winds from forming

• Ocean currents help distribute heat around the world

• Ocean currents remove carbon dioxide from the air

Select the true statements:

• warm water is heavier than cold water

• cold water is heavier than warm water

• salt makes water heavier

• salt makes water lighter

How do winds cause ocean currents?

• Winds push the water on the surface, creating currents

• Winds cause volcanic eruptions, making waves

• Winds do not affect ocean currents

• Winds heat the water
