What is the average height of troposphere?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 13 km.
The average height of the troposphere, the lowest layer of Earth’s atmosphere, is about 13 kilometers (8 miles). However, this height varies depending on location and season. It is thickest at the equator, reaching up to 16–18 kilometers, and thinnest at the poles, around 8–10 kilometers. The troposphere contains most of the atmosphere’s water vapor, weather phenomena, and air mass. It is the layer where all weather changes occur and where life-supporting gases like oxygen are most concentrated.
