The next layer outside the troposphere is the stratosphere. Here the air is much calmer. This is where the airlines fly their planes because the air is calmer and won’t make passengers sick. Ultraviolet radiation from the sun reacts with oxygen to form ozone gas in the stratosphere and helps filter out too much harmful radiation from the sun. This protective layer is called the “ozone layer.”

stratosphere has more than 2,000 illustrated animals. Read about them, color them, label them, learn to draw them.
