Is the amount of oxygen in the air always the same?if yes,how?or if not, how not?
It varies. As Xidike stated, it varies with elevations above the surface and it varies with proximity to sources and sinks. It this, it behaves like almost every other atmospheric gas.adi1998 said:Is the amount of oxygen in the air always the same?if yes,how?or if not, how not?

Humans are not the first lifeform on the planet to pollute themselves to the brink of extinction.
The current balance of oxygen in the atmosphere is approximately 21%. This means that for every 100 molecules of gas in the atmosphere, 21 of them are oxygen molecules.
The balance of oxygen in the atmosphere is maintained through the process of photosynthesis. Plants and other organisms use energy from the sun to convert carbon dioxide and water into oxygen and glucose. This helps to replenish the oxygen in the atmosphere.
Yes, the balance of oxygen in the atmosphere can change due to natural and human activities. Natural events such as volcanic eruptions and forest fires can release large amounts of carbon dioxide into the atmosphere, which can decrease the oxygen levels. Human activities such as deforestation and burning fossil fuels also contribute to changes in the balance of oxygen in the atmosphere.
If the balance of oxygen in the atmosphere is disrupted, it can have serious consequences for living organisms. A decrease in oxygen levels can lead to oxygen deprivation, which can harm or even kill animals and humans. On the other hand, an increase in oxygen levels can also be harmful as it can increase the risk of fires and damage the ozone layer.
The balance of oxygen in the atmosphere is measured using instruments such as gas analyzers and satellites. These devices can accurately measure the concentration of oxygen in the atmosphere and track any changes over time.
