Most gases in the atmosphere are found in the troposphere, which is the lowest layer of Earth's atmosphere, extending from the surface up to about 8 to 15 kilometers (5 to 9 miles) high. This layer contains roughly 75% of the atmosphere's mass and is where weather phenomena occur. Key gases such as nitrogen (78%) and oxygen (21%) are most concentrated in this region. Higher layers, like the stratosphere and mesosphere, have much lower densities of gases.
What else can I help you with?
What are the two most important gasses that make up the atmosphere?
78% Nitrogen,and 21% Oxygen
What are three gasses in the atmosphere?
The 3 important gasses (there are more) are:-NitrogenOxygenCarbon Dioxide
What is the atmosphere of all of the planets made of?
air and gasses and for some no atmosphere
What gasses make up the atmosphere and what percentage does each make up?
The atmosphere is composed of approximatly 79% Nitrogen - 20% Oxygen - 1% Argon and 'other gasses'
Where is most of the gas molecules in the atmosphere found?
The atmosphere is made of gas molecules.
What gasses are the most plentiful in the atmosphere?
Nitrogen and oxygen.
What two most common gasses are found in the atmosphere layers?
The two most common gases found in Earth's atmosphere are nitrogen (N2) and oxygen (O2). Nitrogen makes up about 78% of the atmosphere, while oxygen makes up about 21%.
Where can you find noble gasses in nature?
Noble gases can be found in the atmosphere; the air on Earth is partly composed of the noble gasses.
The mixture of gasses that surround the earth?
Atmosphere. It is a mixture of gasses that surrounds the earth.
What are the two most common gasses that make up the atmosphere?
Nitrogen and oxygen.
The noble gasses are found in column?
The noble gasses are found in the right-most column (group 18) on the period table.
How much air is in Mercury's atmosphere?
Very, very little, as Mercury's atmosphere is almost a vacuum only minute traces of gasses are found.
What is the noble gas that is found in the largest percentage in Earth's atmosphere?
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
What allow Jupiter Saturn Uranus and Neptune to keep most of the gasses in their atmosphere?
gravity
What is the thin envelope of gasses that forms Earth's outer most layer?
The atmosphere (air).
Is the atmosphere a chemical?
No. The atmosphere is a mixture of different gasses.
What is the earth atmosphere is made up of nitrogen?
About 78% of it is nitrogen. Another 21% of the atmosphere is oxygen, and 1% are other gasses found in very small amounts.
