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.

What are he two main components of the atmosphere?
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
What are 2 main ingredients in earth's atmosphere?
Nitrogen and Oxygen account for almost 99% of Earth's atmosphere.
Why does earth have more nitrogen than oxygen in its atmosphere?
The atmosphere of Earth today is not the atmosphere that the planet started out with, the atmosphere has been produced by the biosphere of the planet. Originally the atmosphere was made of hydrocarbons, Carbon Dioxide and Nitrogen. Living things (using photosynthesis) have changed this by using the Carbon Dioxide to make sugars and releasing Oxygen as a waste product. The free Oxygen then got into chemical processes with minerals in the Oceans to make Iron ores and slowly the Ocean and atmosphere changed to include free Oxygen. Nitrogen is very inert and while it is slightly involved in life processes its proportion was unchanged by life. Therefore the composition of the atmosphere is a changing dynamic balance resulting from the nitrogen, and carbon cycles of the planet.
What includes all gases around the earth?
The Earth's atmosphere consists of all the gases that surround the planet, such as nitrogen, oxygen, carbon dioxide, and others.
What makes up Earth's air?
Earth's air is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with traces of other gases such as argon, carbon dioxide, and water vapor. These gases make up the atmosphere, which envelops the planet and is essential for sustaining life.
What planet has nitrogen and oxygen in it's atmosphere?
It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.
Which planet's atmosphere is 78 percent nitrogen?
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
What is the atmosphere made of on planet earth?
It is made out of nitrogen and oxygen
Which planet is rockey and has an atmosphere made up of mainly nitrogen and oxygen?
That planet is Earth.
Which planet has is atmosphere mostly made of nitrogen?
Neptune (NovaNet) There's something wrong here. Neptune is mainly a hydrogen atmosphere. Earth is the planet with a mainly nitrogen atmosphere, but the coldest is Neptune.
What is planet earth atmosphere like?
About 80% Nitrogen and 20% Oxygen.
What planet other than Venus has a nitrogen atmosphere?
Earth's atmosphere is about 79% nitrogen, 20% oxygen, and 1% "other gasses".
What planet's atmosphere is made up of nitrogen with some oxygen?
Earth's atmosphere is made up of 78% nitrogen and 21% oxygen. The other 1% is other gases.
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
What surround a planet?
The gasses surrounding a planet is called an atmosphere and what gasses surround a planet depends on the planet. Earth's atmosphere is a combination of oxygen, nitrogen, argon and carbon dioxide and Saturn's atmosphere is comprised of hydrogen and helium.
Why is nitrogen more than oxygen in the atmosphere?
The atomosphere would be explosive otherwise and the planet uninhabitable. Nitrogen acts as nature's diluent.
What is the scientific term for gases the are surrounding a planet?
The scientific name for the gasses that surround a planet is atmosphere. The atmosphere of earth is made of nitrogen, oxygen, and carbon dioxide.
