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%).
the atmosphere is gas emission from when ground release toxic gases, hydrosphere is tsunamis, lithosphere is the shaking of the earth and avalanches.
Many elements only form through high temperatures and pressures... both of which are present int the Sun - but not in the Earth's atmosphere.
Not all of the elements are present in the Earth's atmosphere.
Mercury has no significant atmosphere
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
Atmosphere, but can be composed of different elements.

The atmosphere itself is NOT an element. The atmosphere is a mixture of all the gases around the planet. Some gases are elements, but because there is more than one gas in the atmosphere, it is a MIXTURE of elements not an element itself.
Mars has an atmosphere that's about 95% carbon dioxide.
The two dominant elements in Earth's atmosphere are nitrogen and oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen accounts for about 21%.
