There are volcanic remains on the moon, why are there no volcanic eruptions now? The reason is not so simple

We all know the moon, which has always been the focus of our human beings since ancient times. However, when modern humans invented the astronomical telescope, we can observe the moon more clearly. Some researchers once believed that the craters on the lunar surface were formed due to volcanic eruptions on the moon. Later, after careful study of the craters on the lunar surface, they came to the conclusion that those craters were actually left after being hit by meteorites. trace.

So are there any volcanic eruptions on the moon? However, some researchers have observed that the occurrence of earthquakes on the moon has always been very frequent, and there are very, very old volcanoes on the moon, but the volcanoes on the moon have not erupted for a long time. So what caused the volcanoes on the moon to not erupt for a long time?

Nowadays, with the continuous progress of science and technology, we have also discovered some very, very old craters on the moon. However, the ages of these craters have been calculated to be more than 3 billion years, and even if the age of the moon is The smallest crater is also 100 million years old, and such a thing is impossible on our earth. Because our earth was born much earlier than the moon, the volcanoes on our earth are still erupting frequently.

And the researchers found through research that the most frequent volcanic eruptions on the moon were when the moon was just formed, and the very famous dark plain on the moon was actually formed after the volcanic eruption was covered by lava, but That was also 3.5 billion years ago. However, the volcanic eruption on the moon is different from the volcanic eruption on our earth. After the volcanic eruption on the moon, a volcanic cone will not be formed. That's because of gravity and other factors, so the traces of volcanic eruptions on the moon will only be a large plain of basalt.

So why do you say that there are no volcanic eruptions on the moon today? This is based on a study of rock samples brought back from the moon by NASA. The results of the study are very surprising, that is, the core rock of the moon is different from the core rock of our earth. The core rock of the moon is inside The main metal contained was actually titanium. Because when the moon was just formed, the volcanoes on the moon would continue to erupt, which would bring a large amount of titanium into the core of the moon. Therefore, the magma that caused the moon is mainly composed of titanium compounds. In this way, the density of the magma inside the moon is too large, so that a large amount of magma is blocked in the interior of the moon and cannot be erupted to the surface of the moon.

But now, as the temperature on the moon is gradually decreasing, and the interior of the moon is melting, maybe we can see volcanoes erupting again on the moon one day in the future.
