Mesosphere - The Mesosphere is middle layer in the atmosphere,elevation is 85km and temperature is 0°C to -90°C.
Stratosphere - The stratosphere is third layer of atmosphere,the airplane is travel in this layer,elevation is 50km and temperature is -50°C to 0°C.
Ozone layer - The ozone layer is Earth's stratosphere that absorbs most of the Sun's UV radiation.
Troposphere- The troposphere is lowest layer of atmosphere,its the layer that we live.The rain and snow is happen in this layer,the elevation is 10km and the temperature is 16°C to -55°C.
