Question
Select the correct answer.What is ozone? A. dissolved oxygen B. the main catalyst in photosynthesis C. a type of oxygen D. a form of calcium carbonate
Solution
The correct answer is C. a type of oxygen. Ozone is a form of oxygen that consists of three oxygen atoms. It is less stable than the diatomic form of oxygen (O2), which is the oxygen we breathe. Ozone (O3) is most commonly known for its presence in the Earth's upper atmosphere, where it forms the ozone layer that protects life on Earth by absorbing the majority of the Sun's harmful ultraviolet radiation.
