Question
Why is troposphere considered to be the most significant layer of the atmosphere ?
Solution
The troposphere is the most important of all the layers of the atmosphere because :
1. All the weather-making processes take place this layer.
2. Great contrast in climate and weather patterns are observed at different altitudes due to changes of temperature in this layer.
3. The presence of the large amount of water vapour in this layer is responsible for condensation, clouds and precipitation.
4. Dust particles give rise to fog, clouds smog, etc. in this layer.
5. Convection currents are formed to this layer for the heating and cooling of the air.
6. The air is unstable in this layer and gives rise to atmospheric disturbances like stormy cyclones.
