Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.

Plants and trees, they convert it to oxygen
Most importantly, carbon dioxide is absorbed by plants in order to photosynthesise. The oxygen is absorbed when plants respire. The atmosphere is the source of rain for their water. Physical aspects of the atmosphere, such as strong winds, can damage plants.
because they have teir own source of gravity and the are out of the earths atmosphere unlike rain drops. stars have built in gravity rain doesnt
Plants
Cyanobacteria are hypothesized to be the early source of free oxygen in Earth's atmosphere through the process of photosynthesis. They evolved around 2.7 billion years ago and played a key role in the Great Oxidation Event, gradually increasing the levels of oxygen in the atmosphere.
Earth's early atmosphere was primarily composed of carbon dioxide. Early bacteria used carbon dioxide as a source of fuel and as a result produced oxygen.
Oxygen in Earth's atmosphere was produced through the process of photosynthesis by cyanobacteria and early algae, starting around 2.5 billion years ago. These organisms converted carbon dioxide and water into glucose and oxygen using sunlight as an energy source. This oxygen began accumulating in the atmosphere and eventually led to the development of the oxygen-rich atmosphere we have today.

I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.

The oxygen in water is the oxygen that is released into the atmosphere.
Oxygen is the major source of photosynthesis in the atmosphere. During photosynthesis, plants and other photosynthetic organisms convert carbon dioxide into oxygen through the process of photosynthesis. This oxygen is then released into the air, replenishing the levels in the atmosphere.
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
