Which layer of atmosphere contains the ozone layer?A. StratosphereB. TroposphereC. ExosphereD. Mesosphere

The ozone layer is found in the Stratosphere. Here's a brief explanation:

Troposphere: This is the layer closest to the Earth's surface, where weather occurs and where most of the Earth's air mass is located. It does not contain the ozone layer.

Stratosphere: This layer lies above the Troposphere and is where the ozone layer is situated. The ozone layer absorbs and scatters ultraviolet (UV) radiation from the sun, which protects living organisms on Earth from harmful UV rays.

Mesosphere: This layer is above the Stratosphere and is where meteoroids burn up upon entering the Earth's atmosphere. It does not contain the ozone layer.

Exosphere: This is the outermost layer of the Earth's atmosphere, where atmospheric particles are very sparse and transition into space. It does not contain the ozone layer.

So, the correct answer is A. Stratosphere.
