1. It is the lowermost layer of the atmosphere. 2. Its height varies from 8 km at the poles to 18 km at the equator. 3. In this layer the temperature decreases at the rate of 1°C per 165 metres. 4. It is a zone of convection currents. 5. Most of the water vapours, clouds and dust particles are found in this layer. 6. Atmospheric disturbances are confined to this zone. |
1. It is the second layer of the atmosphere above the earth. 2. Its height goes upto 50 km. 3. In this layer temperature is very low and mainly constant. 4. It is the non-convective zone of the atmosphere. 5. Clouds, dust particles and water vapours are practically absent in this layer. 6. This zone is free from atmospheric disturbances. |
