    Solution

    The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.
