Oxygen makes up about 21% of the Earth's atmosphere.
Oxygen makes up approximately 21% of the Earth's atmosphere.
The composition of air is approximately 78% nitrogen and 21% oxygen. This balance is a result of Earth's atmospheric conditions and is essential for supporting life on our planet. Other gases, such as argon, carbon dioxide, and trace amounts of other gases, make up the remaining 1% of the atmosphere.
Some common gases that contain oxygen include carbon dioxide (CO2), ozone (O3), and nitrogen dioxide (NO2). These gases contain oxygen in various chemical compositions and play important roles in atmospheric processes.
The air we breathe is approximately 78% nitrogen, 21% oxygen, and the remaining 1% consists of other gases such as carbon dioxide, argon, and trace gases.
One method to liquify atmospheric gases is through a process called cryogenic liquefaction. This involves lowering the temperature of the gases to below their critical temperature, causing them to condense into liquid form. This process is commonly used in industry to produce liquid oxygen, nitrogen, and other gases.
The two main atmospheric gases are nitrogen and oxygen. The approximate percentage for nitrogen is 78% and oxygen's approximate percentage is 21%.

Oxygen makes up approximately 21% of the Earth's atmosphere.
The stratosphere is composed mostly of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include ozone, water vapor, and trace gases like helium and methane. The exact percentages can vary slightly depending on altitude and location.
There is very little oxygen on the Moon's surface, approximately 0.1% of the Earth's oxygen levels. Most of the Moon's atmosphere is composed of argon, helium, and trace amounts of other gases. In order to sustain life, astronauts would need to bring their own supply of oxygen when visiting the Moon.
Algae and cyanobacteria help to keep the balance of atmospheric gases by producing oxygen through photosynthesis and consuming carbon dioxide. This process plays a crucial role in regulating the levels of oxygen and carbon dioxide in the atmosphere, which are essential for life on Earth.
The atmospheric gases essential for life on Earth are oxygen and carbon dioxide. Oxygen is needed for respiration by most organisms, while carbon dioxide is essential for photosynthesis in plants. Both these gases are crucial for the survival of organisms in maintaining the balance of the ecosystem.
