Question

Which of the following gas is found in the Stratosphere?

• A. Ozone
• B. Carbon dioxide
• C. Methane
• D. Hydrogen

Answer 1

The Correct Option is A

The stratosphere is a layer of Earth's atmosphere situated above the troposphere and below the mesosphere. It plays a crucial role in protecting life on Earth by filtering out harmful ultraviolet (UV) radiation from the sun. The gas that is predominantly found in the stratosphere and responsible for this protection is:

• Ozone

Ozone is a form of oxygen with three atoms (O₃), distinct from the O₂ molecule we breathe. It forms the ozone layer, which effectively absorbs and scatters the ultraviolet solar radiation. This makes it critical for sustaining life and keeping ecological balance.

Gas	Presence in Stratosphere
Ozone	High concentration
Carbon dioxide	Not predominant
Methane	Not predominant
Hydrogen	Not predominant

Thus, the correct answer to the question regarding which gas is found in the stratosphere is Ozone. 

Answer 2

The Stratosphere is the second layer of Earth's atmosphere, located above the Troposphere and below the Mesosphere. The ozone layer, which is primarily composed of ozone (O₃), is located in the lower portion of the stratosphere. This ozone layer plays a crucial role in absorbing most of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth.

• Ozone in the stratosphere absorbs UV radiation, and this layer is often referred to as the "ozone layer."
• Carbon dioxide, methane, and hydrogen are not found in significant concentrations in the stratosphere compared to ozone.
