| Consider the following statements with regard to troposphere. |
| 1. Troposphere is higher at the poles than at the equator. |
| 2. All vital atmospheric process leading to various weather and climatic conditions take place in this layer. |
| 3. The increase in temperature with increase in height in this layer is termed as temperature inversion, |
| Which of the statements given above are correct? |
A) 1 and 2
B) 2 and 3
C) 1 and 3
D) All of these
Correct Answer: B
Solution :
[b] Troposphere is higher at equator because heat is transported to greater distance by convectional currents. The layer contains dust particles and over 90% of water droplets. So, all weather phenomena take place in this layer only. All vital atmosphere processes leading to various weather and climatic conditions take place in this layer. Increase in temperature with increase in height in this layer is known as temperature inversion.
