Which gas is the most common in our atmosphere?

• Oxygen

• Nitrogen

• Water Vapor

• Carbon Dioxide

How are the layers in the atmosphere divided?

• It is divided based on if the pressure increases or decreases in the layer

• It is divided into 4 layers of equal height

• It is divided into 4 layers of equal density

• It is divided based on if the temperature increases or decreases in the layer

Which layer has a large amount of ozone?

Why is it BAD if the ozone layer has holes in it?

• Holes would allow less heat to pass through

• Holes in the ozone layer open us up to space, cooling Earth

• Ozone is a carbon dioxide filter, so holes speed up global warming

• Ozone absorbs harmful UV radiation, so holes mean more would get to us.
