The most significant source of oxygen in Earth's atmosphere is photosynthesis by plants, algae, and cyanobacteria. These organisms take in carbon dioxide and water, using sunlight to produce oxygen as a byproduct. This process has been crucial in maintaining the balance of oxygen and carbon dioxide in our atmosphere for billions of years.
What else can I help you with?
What layer of atmosphere holds oxygen in earth?
the layer of the atmosphere that holds oxygen is the troposphere and its pause is tropopause
The second most abundant element in the Earth's atmosphere is?
oxygen
Is most of earth' s atmosphere oxygen?
Most of the oxygen is in the troposphere. Stratosphere contains ozone. It is the converted oxygen.
Is the trophospere the layer of the atmosphere where most nitrogen and oxygen found in?
Yes, the troposphere is the layer of the atmosphere closest to the Earth's surface, and it is where most of the Earth's nitrogen and oxygen are found. This is the layer where weather occurs and where most life on Earth exists.
Oxygen is the most abundant element by volume in Earth's?
Oxygen is the most abundant element in Earth's crust.
The most abundant gases are nitrogen and?
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
What is the second most abundant gas in the Earth's atmosphere?
Oxygen
What layer of atmosphere holds oxygen in earth?
the layer of the atmosphere that holds oxygen is the troposphere and its pause is tropopause
Why is the atmosphere classed as an oxygen atmosphere?
Earth's atmosphere is mainly nitrogen, oxygen, carbon dioxide, and water vapor. Oxygen is the most reactive of these. Oxygen allows all of the life as we know it on earth. Even though oxygen is less than 1/4 of the atmosphere it is the most important part.
The second most abundant element in the Earth's atmosphere is?
oxygen
What is the most aboundant element in earths atmosphere?
I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.
What has the most oxygen in it?
The oxygen molecule, the form of oxygen found in the Earth's atmosphere, is 100% oxygen. There fore it is the material that has the most oxygen in it.
What are the three most abundant elements in th earth's atmosphere and the elements?
These elements are nitrogen, oxygen and argon.
What is the second most abundant gas found in the atmosphere?
The second most abundant gas in the Earth's atmosphere is oxygen, which makes up about 21% of the gases in the atmosphere.
What is the most common element after nitrogen?
Oxygen is the most common element in Earth's atmosphere after nitrogen.
What are the most common gases in earth atmosphere?
The two most common gases in Earth's atmosphere are nitrogen (N) and oxygen (O2). Nitrogen is roughly 78% and oxygen is roughly 21%.
