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.
Which planets atmosphere has nitrogen and oxygen in it?
Earth
What planet has a nitrogen- oxygen atmosphere?
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Find the planets have oxygen in their atmosphere?

Which planet's atmosphere has only 21 percent oxygen?
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 was first responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere have today?
The evolution of photosynthetic bacteria and later on, plants, was responsible for changing the formerly poisonous atmosphere to an oxygen-rich one we have today. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing levels of oxygen in the atmosphere.
How did Earth's atmosphere become rich off oxygen?
Earth's atmosphere became rich in oxygen through a process called photosynthesis, where plants and other organisms use sunlight to convert carbon dioxide and water into oxygen and energy-rich molecules like sugars. Over billions of years, these photosynthetic organisms gradually built up oxygen levels in the atmosphere, leading to the oxygen-rich environment we have today.
Billions of years ago how did the earth come to have an oxygen rich atmosphere?
The oxygen in Earth's atmosphere was likely produced around 2.4 billion years ago by photosynthetic organisms such as cyanobacteria, which released oxygen as a byproduct of photosynthesis. Over time, this oxygen accumulated in the atmosphere, leading to the development of an oxygen-rich environment.
Why would we suffocate on the outer planets?
The outer planets does not have enough oxygen to sustain life, or they don't have an atmosphere at all.
Why do most planets lack seas and ocean?
the lack of oxygen, and h2o in the atmosphere.
Do any other planets have oxygen?
Earth is the only known planet with an oxygenated atmosphere.
What is mercurys atmosphere'?
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
