Atmosphere is divided into 4 layers depending on the temperature gradient in each layer, that is how does the temperature changes (increases or decreases) as we go up away from earth's surface. These four layers (starting with the earth's surface) are: troposphere, stratosphere, mesosphere and thermosphere. With the given data, the troposphere will extend till about 20 km and in this region, temperature will fall rapidly from 15 degrees Celsius to -56 degrees Celsius. The stratosphere will extend from troposphere to about 52 km above the surface. The temperature in this region will increase from -56 degrees Celsius to -2 degrees Celsius. Mesoosphere will extend beyond this region and the temperature will decrease to -86 degrees Celsius and this will be up to 92 km above the earth's surface. Thermosphere will extend beyond that region. 

A graph of height versus temperature will be really helpful in visualizing this trend.

Hope this helps.
