Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
This one...the earth. The other planets are made up of critical gases,like methane, with frozen planets like Pluto made up of layers of frozen gases, such as a suspected layer of oxygen underneath layers of nitrogen and methane, and sulfuric gases which tend to snow out on the cold side of the planet.
Mercury has a thin atmosphere mostly made of oxygen, sodium, hydrogen, helium, and potassium. Venus has a thick atmosphere of carbon dioxide with clouds of sulfuric acid. Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Mercury has virtually no atmosphere. Planet with thinnest Venus has a extremely dense atmosphere of mostly sulphur compared to Earth. Planet with densest. Earth has a moderately dense atmosphere of nearly 3 quarters nitrogen and oxygen. Planet with 2nd from densest. Mars has a thin atmosphere of mostly carbon and some oxygen. Planet with 2nd thinnest.
The low air pressure in the atmosphere is due to the limited amount of gases present, including mostly nitrogen and oxygen. While there is carbon dioxide in the atmosphere, it makes up a small percentage compared to nitrogen and oxygen.
Titan, a moon of Saturn, has a thick atmosphere mainly composed of nitrogen. Jupiter's moon Ganymede has a thin atmosphere made up of oxygen.
Earth
Only one. The one we walk, talk and live on. 78% nitrogen, 21% Oxygen.
Earth. 80% Nitrogen & 20% Oxygen.
No. About 79% is nitrogen.
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.

Mostly Nitrogen, and then Oxygen.
mostly nitrogen with 21% oxygen
mostly nitrogen with 21% oxygen
There is only one in our solar system - the Earth approx 80% nitrogen, 20% oxygen
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
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.
