> LAYERS OF THE ATMOSPHERE
1.
There is a massive blanket that is surrounding the earth and it is called the ATMOSPHERE. It is made up of different gases
mostly nitrogen and oxygen which interact with the other types of gases such as argon, helium, carbon dioxide, neon, water
vapor and dust. The atmosphere is divided into five layers narnely:
A. Troposphere - layer of the atmosphere nearest the earth
The troposphere goes from O km to 16 km.
All weather develops in the troposphere.
B. Stratosphere - the second layer of the atmosphere
The stratosphere goes frorn 16 km to 50 km.
The protective ozone layer is found in this layer that protects us from the ultraviolet radiation of the sun.
C. Mesosphere - the third layer of the atmosphere
The mesosphere goes from 50 km to 90 km.
Meteors burn up in this layer.
Radio waves are reflected to earth in the mesosphere.​
