The atmosphere is 79.9% oxygen.
About 21% of the Earth's atmosphere is oxygen.
The main components of Earth's atmosphere are nitrogen and oxygen. Of these, oxygen is the one we can't live without.
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
While trees play a significant role in producing oxygen, they are not the sole source. Phytoplankton, algae, and other plants also contribute to oxygen production in the atmosphere through photosynthesis. Overall, terrestrial and aquatic ecosystems collectively contribute to the oxygen balance in the atmosphere.
"where the oxygen level increases then combustion takes place"
Photosynthesis by green vegetation and forests.
Processes that increase carbon dioxide in the atmosphere include burning fossil fuels, deforestation, and industrial activities. Photosynthesis by plants and algae is a key process that increases oxygen in the atmosphere.
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.

The atmosphere. As you go higher in elevation, the atmosphere becomes thinner because the air pressure decreases, leading to lower air density.
21% of the atmosphere is oxygen.
The atmosphere is 79.9% oxygen.
The atmosphere becomes highly flammable when the concentration of oxygen reaches about 23.5%. Above this level, the risk of fires and explosions increases significantly.
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
As the distance from the surface increases, the concentration of oxygen in the atmosphere decreases due to lower air pressure. This decrease in oxygen availability can make it harder for living organisms to breathe at higher altitudes.
