Answer:
moon is stone which take light from sum
Answer:
The structure of the Moon has similarities to that of the Earth, and other dissimilarities. The Moon has a core, mantle, and crust, just as the Earth does, but the composition of the core is different. The lunar core has far less iron, and there are no molten components. Without an internal heat source, the Moon is geologically dead, and so too without volcanism or plate tectonic activity. Above the dormant core is a thick mantle composed of the same silicate rock as in the Earth. The Moon's crust has some granitic rock, but more basalt, just as the ocean bottoms of Earth have.
With no geological activity, the surface of the Moon can only be altered by objects that strike it. In the Moon's distant past, the interior was molten, and large impacts would gouge out huge holes. Magma would well up from the interior and fill in the hole, and then smooth over before hardening. Indeed, the maria of the Moon such as Crisium, Tranquilitatis, and Serenitatis are ancient impact craters whose holes were filled with basaltic magma. On the other hand, the Oceanus Procellarum is perhaps a vast lava plain, whose vent by a site called Aristarchus may have erupted lava for millions of years, covering much of the left half of the western hemisphere.
Having a mean density of 3,346.4 kg/m³, the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion years ago.
