Answer 2

Answers regarding atmospheric layers is given below

Troposphere is the region of life of living beings. Above this layer exists stratosphere, which is also known as sunscreen of the earth.

This name is credited to this layer due to presence of ozone layer made up of ozone molecules.

These molecules have special ability to block harmful radiations of sun, thus helping living beings thrive on earth.

Lapse rate in an atmosphere is the quantitative measure of rate of fall in temperature with altitude of earth.

Positive lapse rate is indicative of decrease in temperature with decrease in elevation.

Negative lapse rate indicates increase in temperature on increasing the height above earth.
