The oxygen in Earth's atmosphere comes from photosynthesis, which is carried out by plants and algae. Earth is the only planet known to have life, which is the only way we know of that would cause a planet to have an oxygen-rich atmosphere. Oxygen can form from the chemical breakdown of water via sunlight, but only in trace amounts.
What else can I help you with?
Do any other planets have oxygen?
Earth is the only known planet with an oxygenated atmosphere.
Why is Earth the only planet with oxygen and how is that no other planet does?
Earth is the only planet with abundant oxygen in its atmosphere because it has a unique combination of factors that allow for the presence of oxygen-producing life forms, such as plants. Other planets may lack oxygen due to their distance from the sun, composition of their atmosphere, or absence of life forms that can produce oxygen through photosynthesis.
What planets do not have oxygen?
Mercury, Venus, Mars, and the gas giants Jupiter, Saturn, Uranus, and Neptune do not have oxygen in their atmospheres. These planets have atmospheres composed of different elements and compounds, but oxygen is not a significant component.
Does space have an atmosphere or is it only planets that have them?
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
Why is the atmosphere 78 percent nitrogen and only 21 percent oxygen?
There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen
Do any other planets have oxygen in their atmospheres?
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
Which of the eight planets has the highest percentage of oxygen?
Earth is only one planet where gaseous oxygen is found. The Earth's atmosphere is about 21% Oxygen.
Which planets have oxygen rich atmosphere?
In our solar system there's only one and that's the Earth.
What percent of the Martian atmosphere is oxygen?
Mars' atmosphere contains 0.13% oxygen. Over 95% of the atmosphere on Mars is carbon dioxide.
What planets have oxygen in them?
Almost all the planets have oxygen within them in a chemically combined state {for example: sulphur dioxide, water, etc.}. However, only the Earth has any significant amount of oxygen as a gas, in its atmosphere.
Do any other planets have oxygen?
Earth is the only known planet with an oxygenated atmosphere.
Do any of the planet have oxygen in their atmosphere?
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
Why is Earth the only planet with oxygen and how is that no other planet does?
Earth is the only planet with abundant oxygen in its atmosphere because it has a unique combination of factors that allow for the presence of oxygen-producing life forms, such as plants. Other planets may lack oxygen due to their distance from the sun, composition of their atmosphere, or absence of life forms that can produce oxygen through photosynthesis.
How is atmosphere of earth is different from the other planets?
Earth is the only known planet to have significant amounts of free oxygen in its atmosphere. Also, it's the only planet in our solar system where nitrogen is the main gas in the atmosphere.
What planets do not have oxygen?
Mercury, Venus, Mars, and the gas giants Jupiter, Saturn, Uranus, and Neptune do not have oxygen in their atmospheres. These planets have atmospheres composed of different elements and compounds, but oxygen is not a significant component.
Is it true that 60 percent of the human oxygen?
No, humans do not use or consume 60 percent of the oxygen on Earth. The atmosphere is made up of about 21% oxygen, and human respiration accounts for only a small fraction of that.
Why does Earth only have oxygen?
It doesn't; Earth has many other gasses. Our atmosphere is mostly nitrogen; only about 21% is oxygen. It may be that you intended to ask, why does only Earth have free oxygen in its atmosphere, while other planets in the solar system don't. Free oxygen is produced by green plants (by a process called photosynthesis) and green plants grow only on Earth.
