What are the three layers of the atmosphere and their heights?
Troposphere, Stratosphere, Mesosphere and Thermosphere
There are four important layers of the atmosphere.
The first layer is located between surface (ground zero) and 10-12 km. Of course this is not a constant number because if you are at the poles it is only 5 to 6 km.
The second layer, Stratosphere is situated between 10-12 km and 50 km.
The third one is Mesosphere and is located between 50 km and 85 km.
Finally Thermosphere is located between 85 km and 120 km.
