Layers of the Atmosphere

The atmosphere is divided into 4 main layers. Each layer has unique physical properties. Which is true about the Stratosphere?

• Weather occurs here.

• The Stratosphere is below the Troposphere.

• The Stratosphere has the Ozone layer with a 3-atom molecule of oxygen.

• The Space Shuttle flies in this layer.

What layer is between the Stratosphere and Thermosphere?

• Troposphere

• Exosphere

• Mesosphere
