Question

In the stratosphere, what does screen out a large fraction of the ultraviolet rays of the sun?
(A) $ {H_2} $
(B) $ S{O_2} $
(C) $ CO $
(D) $ HCL $
(E) $ {O_3} $

Answer 1

Hint :In order to answer this question we should. The atmosphere is the gaseous blanket that covers the Earth. Earth's gravitational pull keeps it close to the planet's surface. There would be no life on Earth if the atmosphere did not exist. In comparison to other worlds, the atmosphere keeps the climate on Earth mild.

Complete Step By Step Answer:
The atmosphere is divided into layers according to temperature. The troposphere, stratosphere, mesosphere, and thermosphere are the four layers that make up the atmosphere. The exosphere is an area about $ 500 $ kilometres above the Earth's surface.
The stratosphere, which lies just above the troposphere and below the mesosphere, is the second major layer of the Earth's atmosphere. The temperature of the stratosphere is stratified (layered), with warmer layers higher and colder layers lower to the Earth; this rise in temperature with altitude is caused by the ozone layer's absorption of the Sun's ultraviolet radiation (shortened UV). In comparison, temperature rises with altitude in the troposphere, which is close to the Earth's surface. This temperature inversion occurs at the tropopause, the boundary between the troposphere and the stratosphere.
So, option (E) correct.

Note :
There are some facts about the stratosphere. Facts about the stratosphere and a description of the stratosphere. However, the stratosphere's altitude remains high. With height, the temperature rises. Jets prefer to fly in the Stratosphere. The Stratosphere is home to the ozone layer. In the Stratosphere, swans, cranes, and vultures can fly.
