Yes. The moon is made mostly of rock but has a small nickel-iron core.
rock and iron
The inner planets are mostly made of iron and rock.
Mercury is predominantly composed of metal and rock, with a small iron core. It does not have a significant atmosphere, so it is not mostly gas like the gas giants in our solar system.
A rock containing a lot of iron will likely weather faster than a rock made up mostly of quartz. Iron is prone to oxidation when exposed to moisture and oxygen, leading to rusting and faster deterioration compared to quartz, which is chemically more stable and less reactive.
mostly ice and rock. but some consist of mettle and iron.
Coal. iron ore
Mars. The soil of this planet is rich in iron oxide, which gives the planet a characteristic color. >:)
Gabbro is not typically rich in iron. It is a dark, coarse-grained rock made up mostly of calcium-rich plagioclase feldspar and pyroxene minerals. While it may contain some iron-bearing minerals, it is not considered an iron-rich rock.
Earth's outer core is not made of rock. It is made of molten metal; mostly iron and nickel.
Oddly, Mercury is actually mostly metal. Mercury has a thin rocky crust and a very large iron core.
mostly people say it made of rock but maybe you should write is made of iron
