Question 4
In which layer of the atmosphere does ozone act as a UV radiation shield? (A) Mesosphere (B) Stratosphere (C) Thermosphere (D) Troposphere
Worked Solution & Example Answer:In which layer of the atmosphere does ozone act as a UV radiation shield? (A) Mesosphere (B) Stratosphere (C) Thermosphere (D) Troposphere - HSC - SSCE Chemistry - Question 4 - 2003 - Paper 1
Step 1
Identify the correct layer of the atmosphere
Answer
Ozone primarily acts as a UV radiation shield in the Stratosphere. This layer, located above the Troposphere and below the Mesosphere, contains a high concentration of ozone that absorbs the majority of the sun's harmful ultraviolet (UV) radiation. Therefore, the answer is (B) Stratosphere.
