What are the four main layers of the atmosphere different properties?

Earth’s atmosphere is mainly composed of nitrogen (N) and oxygen (O). This is further subdivided into four layers according to their temperatures. Troposphere the layer closes to the Earth's surface with 10-15 km above its surface. Stratosphere is 15 to 50 km above the surface of the Earth and its top is warmer than its bottom. Mesosphere extends 50 to 80 km and becomes colder with increasing altitude. And thermosphere is 80 km above the surface of the Earth to outer space and is very hot.
