Research by American scientists found that Earth plays an important role in the surface formation of the Moon.
Scientists believe that the gravitational pull of the ancient Earth caused the Moon to be disfigured, causing the equator near the equator to swell.
Because of the various causes of the Moon's distant side, it is still very mysterious. Unlike the Moon's near side, the Moon's far side has very few volcanic plains and is higher than sea level, even some areas reaching tens of thousands of meters.
According to scientists, the distance of the Moon is so high due to the impact of the Earth, particularly due to the gravity of the Earth.
When the Moon formed more than 4 billion years ago, before the Moon's nucleus coalesced, the Moon's surface was a sea of ghosts. During this period the Earth's gravity caused the Moon's surface to be distorted.
This principle is similar to the tidal phenomenon on the Earth's surface caused by the gravitational attraction of the Moon.
