Nitrogen !!! Approximately 79%
The other main gas is oxygen, approximately 20%
The remaining 1% is a mixture of gases , including water vapour, carbon dioxide, the noble(inert) gases, sulpur dioxide, nitrogen oxides, methane.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.
Carbon dioxide makes up the majority of the Martian atmosphere, accounting for about 95% of the gases present.
The atmosphere of Earth is roughly 78% made of nitrogen.
No, Jupiter is a gas giant planet and may have no solid surface at all.
No, our atmosphere is composed mainly of nitrogen (78%). Oxygen comprises around 21% of the atmosphere. Water vapor makes up 1.247% of the atmosphere, the rest being made up of Argon, Carbon dioxide, and trace gases. (The Carbon dioxide protects us from being fried by certain particles flowing from the Sun)
Carbón dioxide gas
This is a little like asking 'Why is iron mostly metal?' Atmospheres are made up of gas.
helium
Which gas is air mostly made up from
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%).
It's rocky, but it has an atmosphere made up mostly of carbon dioxide and has clouds made of sulfuric acid.
Venus is made up of an iron core and rocky mantle. While it's atmosphere mostly consists of carbon dioxide and nitrogen.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.
Dust and gas
The largest planet is Jupiter, with an atmosphere made mostly of hydrogen.
Carbon dioxide makes up the majority of the Martian atmosphere, accounting for about 95% of the gases present.
The atmosphere is made up of 71% nitrogen and 28% oxygen. The other 1% is mostly made up of the noble gas argon.
