What is the composition of mars?

Also like Earth, Mars is a differentiated planet, meaning that it has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. The planet's distinctive red colour is due to the oxidation of iron on its surface. read more

The elemental composition of Mars is different from Earth′s in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. Second, its core is richer in sulphur. read more

Mars is the "Red Planet" for a very good reason: its surface is made of a thick layer of oxidized iron dust and rocks of the same color. Maybe another name for Mars could be "Rusty." But the ruddy surface does not tell the whole story of the composition of this world. Dusty crust. The dust that covers the surface of Mars is fine like talcum powder. read more

Mars has a core that is very similar to the core of Earth. It is comprised of sulfur and iron which is enclosed in a mantle made of silicates. The whole planet is covered by a crust made of iron oxide and basalt and it is the iron oxide that gives the planet its red color. read more
