प्रश्न
Why is the troposphere the most important of all the layers of the atmosphere?
उत्तर
The troposphere is the lowermost layer of the atmosphere. Its average height is 13 km and extends roughly to a height of 8 km near the poles and about 18 km at the equator. It is the most important layer of the atmosphere because:
- Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.
- This layer contains dust particles and water vapour.
- All changes in climate and weather take place in this layer.
- The temperature in this layer decreases at the rate of 1°C for every 165m of height.
- All biological activities take place in this layer.
