The average extension of the troposphere is (in km)………

✅Explanation: The troposphere is the lowest layer of Earth's atmosphere, where most of our weather occurs. The average thickness of the troposphere varies with latitude:
-At the equator, it extends up to about 17-18 km due to warmer temperatures.
-At the poles, it can be as low as 7-8 km due to cooler temperatures.
-On average, the troposphere extends to about 14 km globally.

🛑 🔴Additional information::
-The troposphere layer is the nearest to Earth's surface.
-It contains water-vapor, clouds, and dust.
-The stratosphere is the second layer and ends about 50 km above the earth's surface. 
-"Ozone" is present abundant in the stratosphere.
-The region above the stratosphere is called the "mesosphere" and it starts at 50 km and extends to 85 km high.
-The thermosphere extends from about 90 km to 500 km.
-In this layer, air density is very low.
-The exosphere is the highest layer, and It is above about 500 km.
-It contains the dispersed particles of hydrogen and helium.
