Q. The lowest layer of the atmosphere is:

Explanation by: Mr. Dubey

The Troposphere is the lowest layer of the atmosphere, extending up to 8-15 km above the Earth's surface.

It contains most of the Earth's weather, including clouds, rain, and storms.

The temperature decreases with altitude in this layer.


Other Options Explained:

(A) Stratosphere – Lies above the troposphere and contains the ozone layer.

(B) Thermosphere – A high-altitude layer where the auroras occur.

(D) Mesosphere – Above the stratosphere; meteors burn up here.


Thus, the correct answer is (C) Troposphere.
