Nitrogen, 78% and Oxygen, 21%. There is about 1% of Argon, and trace amounts of other gases.
As this question is in the "Global Warming" section, let me add that these gases are relatively thermodynamically inert. So comparing heat trapping gases against them makes no more sense than comparing the weight of the atmosphere to the weight of earth's oceans.
Our concern is whether the abundance of greenhouse gas in our atmosphere is growing (it is), why that is occurring (human consumption of fossil fuels), and what we ought to do about it--either nothing, if we don't fear the consequences, or considered efforts towards reducing GHG emissions.
What else can I help you with?
What is the gas that makes up 21 of earth's atmosphere?
The gas that makes up 21% of Earth's atmosphere is oxygen.
What gas absorbs UV radiation in the Earth's atmosphere?
Ozone gas absorbs UV radiation in the Earth's atmosphere.
What gas is 21 percent of the Earth's atmosphere?
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
What gas is 78percent of the earth atmosphere?
Nitrogen makes up approximately 78% of the Earth's atmosphere.
Which gas find closest to earth in atmosphere?
The gas closest to Earth in the atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant gas in the atmosphere, comprising around 21%.
Which is the chief gas of atmosphere?
The atmosphere of Earth is roughly 78% made of nitrogen.
How does the composition of earth atmosphere differ from the composition of the atmosphere of the gas giant planet?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
How does the composition of earth's atmosphere differ from the composition of the atmosphere of the gas giant planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
What is not considered a greenhouse gas in the Earth's atmosphere?
Oxygen is not considered a greenhouse gas in the Earth's atmosphere.
How does the composition of Earth's atmosphere differ from the composition of the atmospheres of the gas giant planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
Is Earth atmosphere abundant in gas?
The Earth atmosphere is formed from gases.
What is the scientific name for the layer of gas that surrounds the earth?
The layer of gas that surrounds the Earth is called the atmosphere.
What is the gas that makes up 21 of earth's atmosphere?
The gas that makes up 21% of Earth's atmosphere is oxygen.
What gas absorbs UV radiation in the Earth's atmosphere?
Ozone gas absorbs UV radiation in the Earth's atmosphere.
Is the principle gas in the Venusian atmosphere and also a minor component of the atmosphere of earth and Mars?
There is a bit of confusion here. The Main gas of the atmosphere of Venus, carbon dioxide, is also the main gas of the atmosphere of Mars. This gas is a minor component of Earth's atmosphere.
What gas is 21 percent of the Earth's atmosphere?
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
Which planets gas might be close to the amount on earth?
If by gas you mean an atmosphere, there are no planets with an atmosphere anywhere similar to Earth.
