What if earth had no atmosphere

Would people die? Would everything die? Could the planet recover? Here's a breakdown of what could be expected:. There are two ways human beings could survive losing the atmosphere:. The Earth's magnetic field protects the atmosphere from loss due to solar radiation. Possibly a massive coronal ejection , or solar storm, could burn off the atmosphere. A more likely scenario is atmospheric loss due to a massive meteor impact.

Large impacts have occurred several times on the inner planets, including Earth. Gas molecules gain enough energy to escape the pull of gravity, but only a portion of the atmosphere is lost. Even if the atmosphere ignited, it would be only a chemical reaction changing one type of gas into another. Comforting, right?

Only if you had a pressure suit and oxygen mask on. In order to inhale, your diaphragm uses the pressure difference between the air inside your lungs and the air outside of your body. Everything that needs oxygen would die.

All animals, all plants. That includes everything in the oceans, too. But there would be still some bacteria left. Maybe it would evolve into something intelligent. Eventually, solar radiation would break the water vapor down into oxygen. Combined with carbon dioxide pumped from volcanoes and geothermal vents it would create a new atmosphere. But this would be long after humans were gone — and too thin for us to breathe anyway. Now, take a deep breath, because you can, and relax — no massive meteor or coronal ejection is likely to strip away our atmosphere any time soon.

We hear an awful lot about global warming these days, but what if that concept was taken to the extreme What would it take in order to pull DNA - three letters that represent the building blocks upon which the entire human body is constructed Humans have been digging towards the center of the Earth for decades. Other land animals would follow within a few minutes, plants within a few hours.

Meanwhile, the sudden drop in pressure would have a curious effect on the seas. The absence of pressure would let the fastest-moving molecules escape as gas boil at normal atmospheric temperature; however, as this process continued, only the slowest-moving molecules would be left, so that the rest of the water would very quickly freeze.

Sea levels would drop substantially, but there would still be oxygen dissolved in the water that was left, so sea life, deep-water organisms in particular, might survive longer.
