Earth's atmosphere. Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.

A Cozy Blanket Around The Earth There are layers of different molecules, temperatures, and pressures. Overall, the atmosphere is made up of a few main molecules. The air above you is made of 78% nitrogen (N2), 21% oxygen (O2), 0.9% argon (Ar) and 0.04% carbon dioxide (CO2). That's it.

200 million years ago, the atmosphere stabilised and has remained much the same ever since. As well as nitrogen, the atmosphere contains approximately 21% oxygen and small amounts of other gases such as argon (0.9%) and carbon dioxide (0.04%).

Air is mostly gas So what is air, exactly? It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.

The Earth's atmosphere is the relatively thin layer of gases that surround the planet. It provides us with the oxygen we need to stay alive. The three most abundant gases (the ones with the highest percentages) are all elements: ... 21% oxygen, O.

And depending on the composition of the planet, whether it is a terrestrial or a gas/ice giant, the gases that make up its atmosphere range from either the hydrogen and helium to more complex elements like oxygen, carbon dioxide, ammonia and methane.

Air was considered a “pure” element, but in fact the air that's all around us is made up of a variety of gases: primarily nitrogen and oxygen, with almost 1% argon and even smaller amounts of carbon dioxide and other elements such as krypton and helium. The composition of air is just right for life on Earth, though.
