Which gas is present in a small amount but is important for absorbing ultraviolet rays?
Answer and explanation
Correct answer: Ozone
Ozone is correct because its molecules absorb much of the Sun’s harmful ultraviolet radiation in the stratosphere. Although ozone is present only in trace amounts, the ozone layer reduces the amount of damaging UV-B and UV-C radiation reaching Earth’s surface. Argon and nitrogen do not perform this protective role, while ordinary oxygen is O2 rather than ozone, O3.
