Which elements dominate the fundamental rocky composition of the Moon?

Answer

Oxygen, silicon, magnesium, iron, calcium, and aluminum

When examining the geological makeup of the Moon, its composition is defined by specific elements characteristic of rocky, differentiated bodies. The bulk composition is dominated by six primary elements: oxygen, silicon, magnesium, iron, calcium, and aluminum. These elements combine to form the silicate minerals that constitute the Moon's mantle and crust. This composition contrasts sharply with that of gas giants or comets, reinforcing its nature as a desolate, rocky world.
