Answer 2

Atmosphere

(c)800 km

Atmosphere is a thick blanket of air around earth. The Earth's atmosphere is divided into several layers  named as troposphere$( 12-18\ km)$, stratosphere $(11-50 \ km)$, mesosphere $(50-90 \ km)$, thermosphere $(80-800\ km)$, exosphere $(800-2500\ km)$. These layers are divided on the basis of  temperature.

Ozone layer is mainly present in stratosphere. Each layer has its own benefit and suitability for different purposes.

• Troposphere- lowest part of atmosphere, and contains clouds, rain etc.
• Stratosphere- it contains ozone layer which absorbs harmful radiation.
• Mesosphere-It burns most of the meteors, and asteroids.
• Thermosphere- It is also known as ionosphere, reflects and absorbs radio waves.
• Exosphere-Uppermost region and has no clear boundary.

Note: The ranges of the different layers may vary from source to source.
