Question

in the atmosphere ultraviolet rays are absorbed by

Answer 1

In the atmosphere, ultraviolet rays are absorbed by the ozone layer.

The Earth's atmosphere is divided into five different layers, all of which are very rare. These various atmospheres are the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

The ozone layer is in the Stratosphere.

As sunlight passes through the atmosphere, all UVC and approximately 90% of UVB radiation are absorbed by ozone, water vapour, oxygen, and carbon dioxide. The atmosphere is less affected by UVA. Therefore, the UV radiation reaching the Earth's surface is largely comprised of UVA with a small UVB component.

The ozone layer is a thin part of Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet light. "Ozone holes" are the names of the areas of damage to the ozone layer.

Ozone depletion comprises of two connected events observed since late 1970, a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime reduction in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole.

Hence, the ultraviolet rays are absorbed by the Ozone layer.

Answer 2

Answer:

The absorption of ultraviolet rays in the atmosphere is done by the ozone layer in ozone layer it is done by stratosphere.

Explanation:

The Stratosphere is present above the surface of the troposphere and extends up to the height of 50 kilometers. The good ozone layer is found in the upper part of the atmosphere in the stratosphere.

It acts as a protective shield for the troposphere and protects from UV radiation.

This layer has a dual function of absorption and scattering of UV radiations above the level of ozone.

When UV-C light reaches the stratosphere, it is completely absorbed by oxygen molecules and never reaches the Earth's surface. UV-C splits oxygen molecules into oxygen atoms. These single atoms then react with other oxygen molecules to produce ozone. So, these reactions increase the amount of ozone in the stratosphere.

The absorption of ultraviolet rays in the atmosphere is done by the ozone layer in ozone layer it is done by stratosphere.
