Question

Ozone layer is located in
A. Troposphere
B. Hydrosphere
C. Stratosphere
D. Lithosphere

Answer 1

Hint: This layer that absorbs most of Sun’s UltraViolet rays is called an Ozone layer or ozone shield. Ozone layer is made up of 3 atoms of oxygen. It occurs naturally in the upper atmosphere. It protects life on earth from ultraviolet rays of sun.

Complete answer:
Earth’s atmosphere is divided into various layers, these layers are named as troposphere, stratosphere, mesosphere, thermosphere, ionosphere and exosphere. Troposphere is the nearest most layer to the surface of the earth.

> Option A- Troposphere: The troposphere is the lowest layer of Earth’s atmosphere. This layer has all the weather sites in it. This is below the stratosphere layer and above the earth.

> Option B- Hydrosphere: All the water bodies on the earth’s surface makes up the hydrosphere. Lakes, rivers, ponds, sea and even canals make up the earth's hydrosphere.

> Option C- Stratosphere: It is a major layer of atmosphere of earth, it is the second layer present above the troposphere and below the mesosphere. Most of the ozone layer is concentrated in this layer. This layer is the major layer where the ozone shield is located.

> Option D- Lithosphere: It is part of the biosphere that covers the rigid part of the earth that is land. It consists of a crust and upper mantle part in it.

Hence, the correct answer is option (C).

Note: The ozone layer was discovered by Charles Fabry in 1913. It is present in the stratosphere layer of the atmosphere. It is mainly found in the lower portion of the stratosphere from 15 to 35 kms above earth.
