Earth. To be more exact, Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide.
Plants and many other organisms needs more nitrogen to survive, before they can produce oxygen.

What is the main component of Mars' atmosphere?
Mars has an atmosphere, though it is different than our atmosphere here on Earth. The atmosphere of Mars is thin, cold, and dry and contains much less oxygen than the atmosphere of Earth. The oxygen content of the Martian atmosphere is only 0.13 percent, compared with 21 percent in Earth's atmosphere. Carbon dioxide makes up 95.3 percent of the gas in the atmosphere of Mars. It also contains nitrogen and argon and very small amounts of water and methane. Additionally, the atmospheric pressure on Mars is only about 1/100 that of Earth's!
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 are the most common gases in the atmosphere?
The most common gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, and traces of other gases like neon, helium, and methane.
What percent of Earth's atmosphere is hydrogen?
Although there is an enormous amount of hydrogen contained in Earth's crust and in the waters of the oceans, the free hydrogen in the air is only about 55 parts per million by volume. Because it readily combines with a number of other elements, concentrations are quickly dissipated. Any free hydrogen will rise rapidly into the atmosphere, to be ionized into space : the lighter elements such as hydrogen and helium readily escape the pull of gravity. (Nitrogen and oxygen are heavy enough to be held more readily.)
What planet has an atmosphere is just right for kids?
Earth is the only planet known to have an atmosphere that is just right for kids. It has the right combination of oxygen, nitrogen, and other gases to support human life.
How do we intake only oxygen from the atmosphere?
We dont, we breath nitrogen and oxygen...but only the oxygen gets used by our bodies.
What percent of oxygen is in the thermosphere?
The thermosphere comprises only a tiny fraction of Earth's atmosphere and is mainly composed of oxygen and nitrogen molecules. The percentage of oxygen in the thermosphere is very low, typically less than 0.1%.
What gases from the earths atmosphere are most abundant?
The most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Other gases, such as argon, carbon dioxide, and water vapor, make up the remaining percentage of the atmosphere.
What is the main component of Mars' atmosphere?
Mars has an atmosphere, though it is different than our atmosphere here on Earth. The atmosphere of Mars is thin, cold, and dry and contains much less oxygen than the atmosphere of Earth. The oxygen content of the Martian atmosphere is only 0.13 percent, compared with 21 percent in Earth's atmosphere. Carbon dioxide makes up 95.3 percent of the gas in the atmosphere of Mars. It also contains nitrogen and argon and very small amounts of water and methane. Additionally, the atmospheric pressure on Mars is only about 1/100 that of Earth's!
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.
Are CO2 and Oxygen the only gasses on earth?
No, they're not. In fact, about 78% of the Earth's atmosphere is nitrogen.
What is a component of the earths atmosphere?
One component of the Earth's atmosphere is nitrogen, which makes up about 78% of the atmosphere. Other key components include oxygen (21%) and trace amounts of gases like carbon dioxide, argon, and water vapor.
Is oxygen the only gas found in Earth's atmosphere?
No there is also nitrogen (78%), carbon dioxide and other rare gases in the atmosphere.
Was the atmosphere of the earth always mostly nitrogen and oxygen?
No, the early Earth's atmosphere was primarily composed of carbon dioxide, water vapor, and nitrogen. It was only through processes like photosynthesis that oxygen levels began to increase, eventually leading to the predominantly nitrogen-oxygen mix we have in today's atmosphere.
Which of the 8 major planets has a mostly nitrogen atmosphere?
Only one. The one we walk, talk and live on. 78% nitrogen, 21% Oxygen.
How much of mars atmosphere is made up of oxygen?
Mars' atmosphere is composed of only about 0.13% oxygen, with the majority being carbon dioxide (95.3%), nitrogen (2.7%), and argon (1.6%). This low oxygen level makes it uninhabitable for humans without life support systems.
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.
