Another few billion years, when the old sun volume expansion into a red giant, flames when baking the earth’s surface, it will be the end of life on Earth.

Scientists found that life on earth will not completely extinct, the lithosphere will be their last refuge. Of course, there can only be the last home of the bacteria and other low life.

In fact, we are very lucky, because the sun in the main sequence still a very long period of time. However, over time, the brightness of the sun will be gradually increased. Approximately one billion years after the Earth can begin to feel significant changes. LST began with the passage of time gradually increased, which would increase the amount of water vapor in the atmosphere, rising atmospheric water vapor content of the atmosphere will be further elevated temperatures, this positive feedback effect (negative feedback) will eventually lead to the demise of the vast majority of life on earth.

As the temperature continues to rise, the sea began to accelerate evaporation, loss of lubrication ocean water, the earth plate movement is likely to gradually stop motion, this will lead to volcanic activity ceases lost volcanic activity, atmospheric carbon will not further to add. The lack of carbon dioxide in the atmosphere, plants will not be able to carry out photosynthesis, the atmosphere there will be no supplemental oxygen. Without supplemental oxygen to animals on Earth is a disaster, mammals, and birds will first extinction. Time fish, amphibians and reptiles survive relatively long, they require less oxygen and high temperatures have a strong capacity to endure.

Finally, a higher extinction and other invertebrate life is likely to be, once they finally also can not withstand high temperatures baking, it will return to Earth during the reign of only microbes billions of years ago the.

Then, the resulting back into the rock which will biosphere, where microorganisms can be found in the temporary safety habitat.
