Q. Consider the following statements regarding Troposphere:
1.The height of troposphere is same at poles and equator.
2.The thickness of troposphere is highest at mid latitudes.
3.Most of the changes in climate and weather take place in troposphere.
Choose the correct answer from below given codes:
Answer: D
Notes:
Explanation: 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.
- 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. This is the most important layer for all biological activity.
