Question

The thickness of troposphere is

• A. 12 km
• B. 40km
• C. 8o km
• D. 50 km

Answer 1

The correct option is A 12 km

The atmosphere is made up of five layers mainly, exosphere, thermosphere, mesosphere, stratosphere and troposphere. The thickness of troposphere is measured 12 km. The tropopause is the boundary region between the troposphere and the stratosphere. It is the lowest major atmospheric layer, extending from the Earth's surface up to the bottom of the stratosphere.

So, the correct answer is option A.
