Everything living exposed to atmosphere would die. Some of the non-aerobic organisms would survive so some of the remains would rot. The oceans would boil to produce some sort of atmosphere, then once enough heat was lost, would freeze over...

An essential part of the atmosphere is the ozone layer. It is very important for life on earth. The atmosphere absorbs ultraviolet solar radiation, moderates temperature, and provides useful gases. Depletion of the ozone layer in the atmosp...

SPOILER WARNING: EVERYONE DIES Ok, assuming that you mean it vanishes all at once, and the magnetosphere is unaffected, and that it just disappears into nothing, as opposed to gravity breaking for a second and it all rushing out into space....

We can look at other worlds to see how their atmospheres are affected by certain important substances: dust, carbon dioxide, sulfuric acid. In this way, we can understand what will happen to Earth's atmosphere if natural or human activities continue to introduce these materials into it.

Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen ... The temperature of the Earth's atmosphere varies with altitude; the mathematical relationship between temperature and altitude varies among six different atmospheric layers:

The wind fluctuates as the Sun rotates, alternatively heating the upper air of Earth's atmosphere and allowing it to cool. When the atmosphere is hot, it expands; when it is cool, it contracts.
