उत्तर
| Layers of atmosphere | Distance from earth (approximate) | Basic Function |
| (i) Troposphere | 0 to 10 kilometers | The troposphere contains most of the air and oxygen in the atmosphere. This air is fit for respiration and survival of living organisms. Weather conditions are formed in the troposphere. |
| (ii) Stratosphere | 10 to 50 kilometers | The stratosphere contains the ozone layer which prevents the harmful effects of the sun (U. V. rays) from reaching the earth. |
| (iii) Mesosphere | 50 to 80 kilometers | The mesosphere is a very cold layer and most meteors burn up in this layer and hence are prevented from entering the earth's atmosphere |
| Thermosphere | 80 to 320 kilometers | - |
