Understanding the Troposphere
The troposphere is the lowest layer of Earth's atmosphere, where most weather phenomena occur. Here's a detailed explanation of why option 'A' is correct.
Average Height
- The average height of the troposphere is approximately 13 km (or around 8 miles) above sea level.
- This height can vary depending on geographic location; it is generally higher near the equator and lower at the poles.
Topmost Layer of the Atmosphere
- The troposphere is not the topmost layer; that title belongs to the exosphere.
- The layers of the atmosphere, from the surface outward, include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Temperature Behavior
- In the troposphere, temperature actually decreases with height.
- This is why the higher you go, the colder it gets, leading to phenomena such as the formation of clouds and storms.
Conclusion: Why Option 'A' is Correct
- Given the information above, the only accurate statement among the options is that the average height of the troposphere is 13 km.
- Other statements about it being the topmost layer or that temperature increases with height are incorrect.
In summary, the correct answer is indeed option 'A' due to the precise height of the troposphere, while the other statements contain inaccuracies.

Troposphere
- The average height of the troposphere is 13 km. The troposphere is the lowest layer of the Earth's atmosphere, containing around 80% of its mass and 99 % of its water vapour and aerosols.
- The Troposphere's density is one of its distinguishing characteristics.
- In addition to nitrogen and oxygen, the troposphere contains carbon dioxide, water vapour (almost all of the water vapour in the atmosphere is concentrated in the troposphere), and a variety of other particles.
- The troposphere is where the majority of our weather occurs: clouds, rain, and snow.
- The troposphere is home to nearly all of the air in the atmosphere, as well as nearly all of the water vapour (which forms clouds and rain).
- Its thickness, which tends to vary seasonally, is least at the poles and greatest at the equator.
- The water vapour and particulates of the atmosphere are concentrated in this one layer; they are rarely found in the atmosphere above the troposphere.
Tropospheres Thickness
- The thickness of the troposphere varies across different latitudes of the earth.
- It is thickest in the equator, up to 20 km deep in the tropics, and shallower near the poles, at 7 km.
