The amount of water vapor in the air changes significantly with location and temperature. so a listing of percentage of gasses in the atmosphere would be different depending on how much water was in the air sampled. That would not be useful, because the other gases in the atmosphere do not change all that much.
So it is more helpful to describe the making of the atmosphere as dry air (containing no moisture) and then adjust if needed for the humidity at any one place and time.
"Trace elements" are elements which are present in a sample, but in relatively very small amounts. "Trace gasses" probably means gasses which are present in a sample, but in relatively very small amounts. the gases in earths atmosphere that take up less than 1% volume.
There are more than two gases in the atmosphere. You need to specify the ones you are asking about.
The Earth's early atmosphere consisted of Carrbon Dioxide, methane, sulphur, ammonia, nitrogen and smaller amounts (aprox. 0.05%) of other gases.
Earth contains 21 percent of oxygen in the atmosphere!coz earth contains only hot gases and oxygen is not a hot gas!:D
Variable.
there is 1.25 percent of inert gases in the atmosphere
The Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and trace amounts of other gases such as argon, carbon dioxide, and water vapor. Collectively, these gases make up about 99.96% of the atmosphere, with the remaining 0.04% consisting of various other gases.
Approximately 1% of Earth's atmosphere is made up of gases other than oxygen and nitrogen, including argon, carbon dioxide, and trace amounts of gases like helium, neon, and methane.
Showing the amounts of gases in the atmosphere as percentages of dry air allows for easier comparison and understanding of their relative concentrations. It provides a standardized framework that eliminates the variability that water vapor would introduce, making it simpler to analyze and compare the composition of the atmosphere.
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
The amounts of gases in the atmosphere are usually expressed as percentages to provide a clear and easily understandable representation of their relative abundance. Percentages allow for a straightforward comparison between different gases, highlighting their proportions in relation to the total atmospheric composition. This method also simplifies the communication of data, making it accessible to a wide audience, from scientists to the general public.
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
The atmosphere is composed of gases such as nitrogen (78%), oxygen (21%), argon (0.93%), and trace amounts of carbon dioxide, methane, and other gases. Water vapor is also an important component of the atmosphere.
Nitrogen and oxygen make up the largest percentage of the atmosphere.
Nitrogen
75% nitrogen, 21% oxygen, 3% other gases.
Nitrogen makes up about 78% of the Earth's atmosphere, while oxygen makes up about 21%. The remaining 1% consists of other gases such as argon, carbon dioxide, and trace amounts of other gases.
