Explain breifly the diffrent layer of …

There are five layers of atmosphere , 1. Troposphere This is the sphere in which weather condition changes occur . It extend upto 0 to 12 km . 2. Stratorsphere It lies above troposphere and extend upto 80 km .it is warm tempereture and dry air this layer is almost free from cloud .It absorb the ultraviolet rays . 3.Mesosphere It exend upto 50 km.In this layer temperature start to decrease with height .meteorite burn up there due to the friction and presence of some oxygen . 4. Thermosphere It extend upto 80 to 700 km.In this sphere temperature increse rapidly with height . This layer contains electrally charged particles called ions. 5. Exoxsphere It extend upto 700 to 10000 km .This is layer where many man made satellite orbit the earth. This air is very thin containing helium and hydrogen .
