The Greenhouse Effect

The gas that is most abundant in the atmosphere is

• oxygen
• nitrogen
• carbon dioxide
• argon

What absorbs ultraviolet rays in the atmosphere?

• troposphere
• stratosphere
• ozone layer
• greenhouse gases

Where is the ozone located?

• troposphere
• stratosphere
• mesosphere
• thermosphere

What chemical is responsible for breaking up the ozone?

• Carbon Dioxide
• Nitrogen
• Oxygen

Why does too much carbon dioxide in the atmosphere cause climate change?

• It cools down our planet.
• It blocks out UV rays.
• It traps heat and warms up our planet.
• It lets sunlight escape.
