What is inferred to be the main source of the free oxygen that first entered earth's atmosphere?
The main source of free oxygen that first entered Earth's atmosphere is believed to be the process of photosynthesis by ancient cyanobacteria, also known as blue-green algae, around 2.5 to 3.5 billion years ago. These microorganisms converted carbon dioxide and water into oxygen and organic compounds, gradually increasing the oxygen levels in the atmosphere.
Does sodium nitrate burn in an oxygen free atmosphere?
No, sodium nitrate does not burn in an oxygen-free atmosphere because combustion requires oxygen to support the chemical reaction that produces heat and light. Without oxygen, there is no source for the combustion reaction to occur.
The primitive earth's atmosphere did not contain water vapor free nitrogen free hydrogen free oxygen inert gases?
The primitive earth's atmosphere contained mainly water vapor, carbon dioxide, nitrogen, and small amounts of other gases like methane and ammonia. It did not have free oxygen as it was produced later by photosynthetic organisms. Nitrogen and inert gases like argon were also present in the early atmosphere.
Where does the free oxygen in Earths atmosphere come from?
The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.
How did free oxygen come about in the atmosphere?
Free oxygen accumulated in Earth's atmosphere around 2.4 billion years ago due to the process of photosynthesis by early cyanobacteria. These organisms produced oxygen as a byproduct of converting sunlight and carbon dioxide into energy. Over time, oxygen levels increased, leading to the oxygen-rich atmosphere we have today.
What is hypothesized to be the early source of free oxygen in Earth's atmosphere?
cyanobacteria
Hypothesized to be the early source of free oxygen in Earth's atmosphere?
Cyanobacteria are hypothesized to be the early source of free oxygen in Earth's atmosphere through the process of photosynthesis. They evolved around 2.7 billion years ago and played a key role in the Great Oxidation Event, gradually increasing the levels of oxygen in the atmosphere.
What is inferred to be the main source of the free oxygen that first entered earth?
oxygen producing organisms
Why was oxygen absent from earth's early atmosphere?
Oxygen is an extremely chemically active element, which is why things can burn in our current atmosphere. In the early Earth, all the oxygen had reacted with other chemicals in the environment, so that there was no free oxygen. Only later, when photosynthesis was used by green plants, was there a source of free oxygen.

How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
The primative earths atmosphere did not contain?
Free oxygen
What is the water in photosynthesis?
The source of the electron pair that removes the oxygen from the CO2 and lets it free to the Atmosphere, and binds the hydrogen to carbon. Also known as a reducing agent.
Can you breathe Jupiter's atmosphere?
No. Jupiter's atmosphere is mostly hydrogen and helium with no free oxygen.
How much of the atmosphere of the is free of nitrogen?
32% the of the atmosphere is Argon, Oxygen and Other stuff
