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.
No, the atmosphere does not get thicker as you go higher; it actually becomes thinner. As altitude increases, the air pressure decreases, leading to a lower concentration of air molecules. This means that at higher elevations, the atmosphere is less dense, resulting in less oxygen and lower overall air pressure.
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.
"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 process in which oxygen increases and carbon dioxide decreases in plants is called photosynthesis. During photosynthesis, plants absorb carbon dioxide from the atmosphere and water from the soil, using sunlight as energy to convert these into glucose and oxygen. The oxygen is released as a byproduct into the atmosphere, while the glucose is utilized for energy and growth. This process not only sustains the plant itself but also contributes to maintaining atmospheric balance.
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.
