Oxygen gas became part of the atmosphere througha process called the Great Oxidation Event, which occurred around 2.4 billion years ago due to the activities of early photosynthetic organisms, such as cyanobacteria. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing oxygen levels in the atmosphere.
What else can I help you with?
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 not considered a greenhouse gas in the Earth's atmosphere?
Oxygen is not considered a greenhouse gas in the Earth's atmosphere.
What gas in the atmosphere important to respiration?
Oxygen is the gas in the atmosphere that is important for respiration. It is needed by cells to generate energy through the process of cellular respiration.
What type of gas is released by plants to the atmosphere?
Plants release oxygen gas (O2) into the atmosphere as a byproduct of photosynthesis.
Does the atmosphere contain hydrogen gas?
Yes, the atmosphere contains trace amounts of hydrogen gas, but it is primarily composed of nitrogen (78%) and oxygen (21%). Hydrogen gas is much less abundant in the atmosphere compared to nitrogen and oxygen.
What gas was not part of early earths atmosphere?
oxygen
What gas is 21 percent of earth atmosphere?
Oxygen
Besides nitrogen and oxygen what other gas is part of our air?
Argon is another gas that is part of Earth's atmosphere. It makes up about 0.93% of the atmosphere and is the third most abundant gas after nitrogen and oxygen. It is chemically inert and contributes to the overall composition and stability of the atmosphere.
Is it true that earth's atmosphere is composed of liquid oxygen?
The atmosphere of the Earth is a gas, not a liquid, and although it does contain oxygen, that is just one part of the atmosphere, which is mostly nitrogen.
What common gas was not part of Earth's original atmosphere?
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
What gas does the plant put back into the atmosphere and who uses the gas?
The plant put back oxygen into the atmosphere and the humans (us) use the oxygen to breathe Oxygen is used by all living things as well as playing a part in oxidization Fire corrosion etc
What gas in our atmosphere promotes combustion?
Oxygen
What gas is 21 percent of the Earth's atmosphere?
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
What important gas is part of earth s atmosphere?
I'd say the most important gasses in the Earth's atmosphere are oxygen and water vapour.
Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?
Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.
What gas in atmosphere is needed by the body?
1.lpg gas that the atmosphere reveal on its own self
Which gas in the atmosphere is the second most abundant gas?
Oxygen is the second most abundant gas in Earth's atmosphere, making up about 21% of the air we breathe.
