Probably the Moon really has a core, though it is relatively small – only two percent of its mass and is a little bit bigger than 400 miles wide. It has lots of iron, but I also filled with lots of other compounds.
The rocky mantle of the Moon is approximately 825 miles in density which consists of rocks full of magnesium and iron. There were some continuous lunar volcanic eruptions more than 4 billion years ago that led to the thick layer of magma mantle on its surface.
The lunar surface is more than 40 miles in depth. The vast majority of the surface is broken or has some damages, due to strong impact form other space objects. The depth of the cracks of the surface reaches almost 6 miles.
The Moon is very textured and uneven, it is rocky and damaged by outer space object that collided into it After the asteroids collided on its surface the huge craters were created, as there is no atmosphere on the Moon, the craters are not changed after they are formed.
The surface of the Moon has certain contents and by weight it is approximately 43 % O2, 20% Si, 19% Mg, 10 % Fe, 3% Ca, 3% Al, 0.42% Cr, 0.18% Ti and 0.12% Mn.
Scientists have investigated the surface of the Moon and have found the features that indicate the water presence on the Moon. It could be from the time he Moon separated from Earth or the water might be deep down inside the Moon. Special equipment works on the Moon to get more precise information and samples.
The studies showed that the traces of water are more numerous on the southern part of the Moon, according to Lunar Reconnaissance Orbiter. However, scientists also say that the amount of water on the Moon might be really scarce. Also, there is some evidence on the water on the surface of the Moon, but results of this study will be known soon.
