Originally the earth had only a small amount of oxygen and abundant carbon dioxide. Primordial green algae first evolved to take advantage of this carbon dioxide and produced the oxygen as a by product. Over billions and billions of years, and as additional plant species evolved, the atmosphere was transformed into the oxygen rich environment we have today.

What three planets of your solar system show signs of oxygen in their atmosphere?
Earth, Mars, and Venus are the three planets in our solar system that show signs of oxygen in their atmosphere, although the levels and presence of oxygen vary significantly among them. Earth has a rich oxygen atmosphere, while Mars and Venus have much lower levels of oxygen.
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.
Do other planets have oxygen besides earth?
There is no evidence of significant amounts of free oxygen on planets other than Earth. Oxygen is produced on Earth through photosynthesis by plants and other organisms. Different planets have different compositions of gases in their atmospheres, such as carbon dioxide, nitrogen, and methane.
Do any other planets have oxygen?
Earth is the only known planet with an oxygenated atmosphere.
Is there oxygen on the planet?
Earth, Mars and Mercury are the planets that have oxygen on them.
Which planets atmosphere has nitrogen and oxygen in it?
Earth
How is there oxygen on earth but not on other planets?
This is because there is absolutely no trees on other planets.Mean while the trees are the propagators of oxygen on earth.hence the absence of oxygen on other planets.
Do planets have Ozone?
Earth has an ozone layer in atmosphere. It is present in the stratospheric region. Other planets which have oxygen in their environment might have ozone.Some planets like earth do. Others might have.
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.
What solar syatem planets have oxygen?
Earth and Mars has full of oxygen in the solar system!!!!!!
What planets atomspere is mostly nitrogen and oxygen?
Earth. 80% Nitrogen & 20% Oxygen.
Do all of the rocky planets have oxygen?
No. Only Earth has a significant amount of oxygen. (I guess you mean oxygen as the gaseous element. Oxygen does occur on other planets in compounds like carbon dioxide.)
What planets are mostly made up of nitrogenand oxygen?
The Earth approx. 80% nitrogen 20 % oxygen
What three planets of your solar system show signs of oxygen in their atmosphere?
Earth, Mars, and Venus are the three planets in our solar system that show signs of oxygen in their atmosphere, although the levels and presence of oxygen vary significantly among them. Earth has a rich oxygen atmosphere, while Mars and Venus have much lower levels of oxygen.
Why earth has oxygen and not other planets?
Earth has oxygen because of the process of photosynthesis carried out by plants and other photosynthetic organisms. These organisms convert carbon dioxide into oxygen, resulting in the high levels of oxygen in Earth's atmosphere. Other planets may not have abundant oxygen due to different composition, lack of photosynthetic life forms, or processes that have altered their atmosphere over time.
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.
