Question

Assertion (A): Ozone at higher levels of atmosphere is a product of UV radiation acting on oxygen molecule.

Reason (R): The higher energy of UV splits apart some molecular O₂.

पर्याय

• Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both, Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both, Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Explanation:

In the upper atmosphere, UV radiation splits O₂ molecules into oxygen atoms, which then combine with O₂ to form ozone (O₃). Thus, the Reason correctly explains how ozone is formed, making both statements true and related.
