If the earth is tidally locked by the sun, there will be a phenomenon of eternal night and eternal day, how will species survive?

The reason why the earth can have four seasons all year round, and the reason why day and night alternate, is precisely because the earth revolves around the sun. Just imagine if one day the earth no longer revolves around the sun, or if one day there is a tidal lock between the earth and the sun like the tidal locking of the moon and the earth, causing the earth to always keep one side facing the sun and the other One side is always in darkness, and life can continue at that time.

Almost all life on earth depends on such a stable ecological environment.

In fact, according to scientists' calculations, the Earth's rotation is gradually slowing down, which means that one day, the Earth will be tidally locked to the Sun. But this time is 7 billion years later.

Then let's imagine, if such a change really happens, one side of the earth is day and the other side is night, what impact will it have on life on earth?

If tidal locking occurs, the temperature on the side facing the sun will rise in a straight line because it is constantly illuminated. Scientists predict that it will reach above 70 degrees Celsius in the early stage, while the dark side facing the sun lacks sunlight and the temperature will drop to below minus 40 degrees Celsius.

Of course, because there is a "padded coat" of the atmosphere on the surface of the earth, the temperature on the front of the earth and the temperature on the back of the earth will not be very different. (The moon has no atmosphere, and the temperature difference between the front and back is as high as several hundred degrees Celsius)

The uninterrupted irradiation of the sun on the front of the earth causes a large amount of liquid water to evaporate. These warm and humid air flows will convect with the cold air on the back, causing heavy rainfall and super storms. At that time, only the intermediate zone where the polar day and the polar night meet can be suitable for biological survival, and all human countries will continue to fight in order to seize the habitable zone.

As for other creatures, because they lack the ability to migrate long distances and cannot adapt to the new ecological environment, most of them will become extinct in a short period of time, and there may be only a very small number of creatures that can continue to survive. But the harsh ecological environment will continue to "eliminate" all living things.

The most terrifying thing is not the change of the ecological environment, but once the earth is locked by the solar tide, it will lead to the disappearance of the earth's magnetic field.

What kind of consequences will the disappearance of the earth's magnetic field lead to? Just refer to the moon to know. At that time, the last protective layer (atmosphere) of the earth will be continuously peeled off by the solar wind without the adsorption of the earth's magnetic field. In the end, the earth is "undressed" and exposed in the universe. Without the protection of the atmosphere, basically all life will be extinct.
