Start Getting Noticed


The outer surface of Mars is mostly basalt, brought to the surface by volcanoes in the planet’s early history. This volcanic activity ceased many years ago, and now much of the surface is covered by fine iron oxide dust with the consistency of talcum powder. Planetary scientists think that Mars has a core region which consists mostly of iron.

The core is surrounded by a mantle that once was active, but is now dormant. The mantle of Mars is made of silicates. If the core is liquid, the mantle is more like a soft rock paste – less dense than the core. It’s then surrounded by a crust that varies in thickness.
