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.
Earth is the planet that fits this description. It contains approximately 70% water on its surface and its atmosphere is primarily composed of nitrogen, with oxygen being the second most abundant gas.
That planet is Earth.
None. By definition a rocky planet is mostly rock. Venus, by far, has the densest atmosphere of the terrestrial planets, but the planet itself is mostly rock and is similar in composition to Earth.
The inner planet that has an atmosphere containing mostly carbon dioxide is Venus. It has an extremely dense atmosphere, made up mostly of carbon dioxide with small amounts of nitrogen and trace amounts of other gases. The thick atmosphere contributes to Venus' extreme greenhouse effect, making it the hottest planet in the solar system.
The atmosphere of Earth contains about 78.08% nitrogen. There has been no other place found that has this nitrogen in abundance, with Mars having only 3% as a remainder of its thin and low-pressure atmosphere.

It is made out of nitrogen and oxygen
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.
That planet is Earth.
The atmosphere is made up of 71% nitrogen and 28% oxygen. The other 1% is mostly made up of the noble gas argon.
Earth's atmosphere is mostly made up of nitrogen, which makes up 79 percent. The atmosphere contains 20 percent oxygen and 1 percent other gases.

Venus
Earth's atmosphere is made up of 78% nitrogen and 21% oxygen. The other 1% is other gases.
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
