There is only about 2 years remaining. Starting next year, half of you will need to stop breathing every other day.
just kidding. The atmosphere does not run out. It is replenished by green plants that make oxygen as part of photosynthesis. You may resume breathing now.
1000 millions years ago.
no, but we think it might have done many millions of years ago
Pluto has:5 moonsNo ringsOnly has a temporary thin atmosphere during its "summer" years when it is closer to the sun and the surface ice evaporates.
After many years, as rocks are eroded, gases trapped in them will be released into the atmosphere so in a way rocks are "storage rooms" for gases just as our Earth is.
Venus has a very thick and acid filled atmosphere. The atmosphere of Venus is very dangerous to space probes. Over the years we have sent many probes to Venus but the corrosive acid and heavy atmosphere destroys them practically before they get to the surface!
There is no exact answer yet to this question. If we stopped producing carbon dioxide (CO2) now, the extra CO2 we have added to the atmosphere would probably stay there for many many years. The InterGovernmental Panel on Climate Change (IPCC) in its 2007 report, talking about the increased levels of carbon dioxide, says, "About 50% of a CO2 increase will be removed from the atmosphere within 30 years, and a further 30% will be removed within a few centuries. The remaining 20% may stay in the atmosphere for many thousands of years." Read more at the link below.
Why are there so many layers in the atmosphere
It varies - from a few centuries to a few billion years. But its not a meteor until it hits an atmosphere (a matter of a few seconds to minutes).
After plants developed chlorophyll and multiplied to the point where they could "pollute" the primal atmosphere, somewhere between 1 and 2 billion years ago.
No, actually it took a period of about 2.5 billion years for the atmosphere to be were it is today.
The atmosphere of the planet is not noticeably different now to how it was 4000 years ago.
Oxygen is the element that transformed Carbon Dioxide atmosphere a billion years ago to what you breathe.
