Q. What does 'Ozone Layer' absorb

Explanation by: Official MCQ Buddy

The ozone layer in Earth's stratosphere absorbs ultraviolet (UV) radiation from the Sun, preventing most of it from reaching the Earth's surface. This protects living organisms from harmful UV radiation, which can cause skin cancer, cataracts, and DNA damage.
(A) X-rays – Incorrect; X-rays are absorbed mostly by the Earth's atmosphere.
(B) Gamma (γ) rays – Incorrect; these are absorbed by the upper atmosphere.
(C) Infrared rays – Incorrect; the ozone layer does not primarily absorb infrared radiation.
Thus, the ozone layer absorbs ultraviolet (UV) rays, making option (D) Ultraviolet rays the correct answer.
