How is oxygen formed?
There are two ways in which oxygen is formed in nature. They are: 1 Photosynthesis: It is a complex process used by green plants where the leaves of the green plants with the help of sunlight and chlorophyll convert carbon dioxide and water into glucose and oxygen. The glucose produced is transferred to the fruits and edible parts of the plant. As already explained, the oxygen released into the atmosphere as a by-product of this process. 2 Photodissociation: It is the formation of oxygen molecules when sunlight interacts with the water vapor present in the atmosphere. Water vapor exists in the atmosphere as a result of the water cycle. The destruction of the ozone layer by various gases can also lead to the formation of molecular oxygen.
