-
A.
Infrared rays
-
B.
Gamma rays
-
C.
X rays
-
D.
Ultraviolet rays
Correct Answer:
D. Ultraviolet rays
Explanation:
The ozone layer, located in the stratosphere, acts as a protective shield for Earth by absorbing 97 to 99 percent of the sun's high-energy ultraviolet (UV) radiation. Specifically, it is highly efficient at screening out UV-B and UV-C rays, which are known to cause significant biological damage. Without this filtration, these rays would reach the surface and harm living organisms by damaging DNA, causing skin cancers and cataracts, and disrupting various ecosystems. While the atmosphere also interacts with other types of radiation, such as infrared and X-rays, the primary role of the ozone layer in sustaining life is the absorption of harmful ultraviolet rays.
