Stratosphere
Earth's Layers
The stratosphere is one of the layers of Earth's atmosphere, not the surface or space.

Weather balloons can rise up into the stratosphere to gather data.
Ozone Significance
The stratosphere is important for its ozone layer, which protects us from the sun's harmful ultraviolet rays.

Scientists study the stratosphere to monitor changes in the ozone layer.
Commercial Flight
Commercial airplanes often fly in the lower stratosphere to avoid weather disturbances from the troposphere.

Our flight will cruise in the stratosphere for smoother travel.
