The troposphere __________________?

• consists of a blanket of ozone gas which protects us from the harmful rays of the sun. It is almost free from clouds and weather phenomenon, thus making a condition suitable for flying airplanes.

• is a layer in which meteorites burn up, after entering from the space.

• consists of the air we breathe, and almost all the weather phenomena like rainfall, hailstorms, etc. take place here. It is thus the most important layer.
