It depends which atmosphere you mean.
The Earth's atmosphere is (not counting water vapour, which varies between 1 and 5% at the surface) 78% nitrogen, 20% oxygen, 1% argon and 1% other gasses (mainly carbon dioxide)
It is divided into many layers. The lowest is the troposphere, where all the weather happens and is the part planes fly in. Directly above that is the stratosphere and above that is the mesosphere. Then the thermosphere (this is seriously high, we're talking space stations and shuttles now). And finally the exosphere, which is mainly hydrogen and helium.
Within these layers are other divisions like the ozone layer in the stratosphere where almost all of the ozone is found.
Mars' atmosphere is very dry and composed mainly of carbon dioxide.
Venus' is very dense and sulphur-rich.
Jupiter and Saturn both have largely hydrogen and helium bases atmospheres while Saturn's moon Titan has a very thick atmosphere made up almost entirely of nitrogen.
Actally Saturn does not have an atmosphere at all. Its 7 rings each have there own atmosphere.
Mars has an extremely thin atmosphere made of carbon dioxide.
The atmosphere is a mixture of gases that surrounds Earth. It appears transparent to the naked eye, but when viewed from space, it appears as a thin layer of blue due to the scattering of sunlight in the atmosphere.
Titan is the only one of Saturn's moons that has an appreciable atmosphere. It is most like earth's atmosphere in its high concentration of nitrogen (98% compared to Earth's 78%).
Like all weather hurricanes occur in the troposphere, the lowest layer of the atmosphere.
No. The moon does not have an atmosphere.
Actally Saturn does not have an atmosphere at all. Its 7 rings each have there own atmosphere.
There is not much atmosphere on earth
No
No
None. If it had an "atmosphere" like the Sun, it would have to be a star, itself, like the Sun is, not a planet.
No, the Moon does not have an atmosphere like Earth's. It has a very thin exosphere that consists of small amounts of gases and particles, but it does not have a significant atmosphere like Earth with air and water.
the earth atmosphere surrounds us like a giant ball
mercury has no atmosphere which means it is nothing like earths.
The atmosphere was rather quiet and uncertain.
The atmosphere covers the Earth like a blanket.
The Moon's atmosphere is like . . . nothing. There isn't one. The Moon does not have enough gravity to hold onto an atmosphere while the Sun is successfully making any atmosphere dissipate into space.
