We know what the moon looks like on the outside from Earth,and we've seen numerous photographs of its surface, but what's the inside of the moon like? If we follow the Theory of the Great Impact, the Moon was formed from the pieces tacked by the blow of a huge object against Earth. In this way we can know about how it was formed, and how it should be inside.
Interested in moon topic? so must check out The Different Languages which tells that how to say moon in different languages in almost 88 languages. The closest tests we have are the samples the Apollo took on his journey to the Moon, and the lunar meteorites that have fallen on Earth.
If we take them as a base, we can know that the Moon is mostly made up of rocks of 4.5 billion years, magmatic rocks, created from volcanoes that erupted 3.85 billion years ago, basaltic rocks and gaps, rocks that were formed by the impact of asteroids and meteorites.
Inside of the moon
The interior of the Moon consists of an iron core, followed by a semi-solid mantle, a stiff mantle and hard bark on the outside. If we compare the interior of the Moon with that of Earth, we can see that it is much colder. Because it is much smaller, it loses heat easily in space.
Only the semi-solid mantle can flow, because the layers closest to the surface are too hard to move. The nucleus is made up of iron and makes up only 2 to 4% of the total mass of the Moon. Unlike Earth's, it doesn't create a very large magnetic field. If we wanted to use a compass we couldn't, because there's not enough magnetism.

Latest studies of the lunar surface
The last information received by the seismographs left by the Apollo on the Moon came in 1977. Through movements on the rocks, such as those of earthquakes, its composition could be studied. What they discovered was that these movements fractured the layers between the nucleus and the cortex.
One of the recurring questions has to do with the basalt seas that erupted. The moon solidified long before these eruptions. The possible response is due to the heating of elements such as uranium and thorium, in a process known as mantle overturning.
This occurred because the highest layers of the Moon had dense minerals, but the layers below were less dense, which led to gravitational instability. The higher layers sank to correct this problem, making them closer to the surface and melted by pressure.
There is still a long way to go when it comes to study the Moon. It's not easy to get samples or study it carefully, but much of itshi story can be helpful in better understanding Earth. While the Earth has been highly modified, the Moon remains the same over the years, and can give us clues about its internal formation, and the formation of other planets.
