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

We all know the moon, which has attracted the attention of human beings since ancient times. However, when modern humans invented astronomical telescopes, we can observe the moon more clearly. And some researchers once believed that the craters on the surface of the moon were formed due to volcanic eruptions on the moon. Later, after careful study of the craters on the surface of the moon, they concluded that those craters were actually left after being hit by meteorites. trace.

So have there been volcanic eruptions on the moon? However, some scientific researchers have observed that earthquakes on the moon have always occurred very frequently, and there are also very, very old volcanoes on the moon, but those 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 advancement of science and technology, we humans have also discovered some very, very old craters on the moon. However, the ages of these craters are calculated to be more than 3 billion years old, and even if the age of the moon is The smallest crater is 100 million years old. Such a thing is impossible on our earth. Because our earth was born much earlier than the moon, but the volcanoes on our earth are still erupting frequently.

And researchers have discovered through research that the most frequent volcanic eruptions on the moon are when the moon was just formed, and the famous dark plain on the moon is actually formed by lava after volcanic eruptions, 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, no volcanic cone will 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.

Then why do you say that there are no volcanic eruptions on the moon now? This is based on a study of the rock samples brought back by NASA from the moon. The results of the study are very surprising, that is, the core rocks of the moon are different from the core rocks of our earth. The interior of the core rocks of the moon The main metal contained is actually titanium. Because when the moon was just formed, the volcanoes on the moon would continue to erupt, which would cause a large amount of titanium to be brought into the core of the moon. Therefore, the magma that caused the moon is mainly composed of titanium compounds. This makes the magma density inside the moon too high, which causes a large amount of magma to be 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 dropping, and the interior of the moon is melting more and more, perhaps we will be able to see volcanoes re-erupting on the moon someday in the future.
