Answer:
There are no options in this question, however, the answer is:
Ultraviolet radiation
Step-by-step explanation:
Ozone is a molecule composed of three oxygen atoms (O3). Ozone, forms a layer called OZONE LAYER in the part of the Earth's atmosphere called STRATOSPHERE. This ozone is formed when an oxygen atom (broken from a molecule by UV light) combines with an oxygen molecule.
The ozone layer in the stratosphere helps to prevent the detrimental ultraviolet radiation from the SUN from reaching the Earth. The ozone molecule does this by absorbing the UV radiation before it reaches the Earth. Hence, ozone molecules are good for the earth because they absorb ultraviolet (UV) radiation.
