Troposphere: The troposphere is the lowermost layer of the atmosphere. Its average height is 13 km and extends roughly to a height of 8 km near the poles and about 18 km at the equator. The thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer. The temperature in this layer decreases at the rate for every 165 km of height.  Stratosphere: The stratosphere is found above the tropopause and extends up to a height of 50 km. One important feature of the stratosphere is that it contains the ozone layer. This layer absorbs ultra-violet radiation and shields life on the earth from an intense, harmful form of energy.  Mesosphere: The mesosphere lies above the stratosphere, which extends up to a height of 80 km. In this layer, the temperature starts decreasing with the increase in altitude and reaches up to minus 100 km at a height of 80 km. Thermosphere: The thermosphere is located between 80 and 400 km above the mesosphere. It contains electrically charged particles known as ions, and hence, it is known as the ionosphere. Radio waves transmitted from the earth are reflected back to the earth by this layer. The temperature here starts increasing with height. Exosphere: The uppermost layer of the atmosphere above the thermosphere is known as the exosphere. This is the highest layer but very little is known about it.
