From the Earth s surface through the bottom layer of atmosphere, called the troposphere, temperature decreases with altitude. Weather occurs in this layer. It s also the layer we live in. The next layer up is called the stratosphere. In the stratosphere, temperature increases with altitude. This is because of ozone. When the ozone in this layer absorbs UV light from the sun, it increases in temperature. In the mesosphere, ozone concentration decreases.
