GENERAL FEATURES OF THE INTERNAL STRUCTURE OF THE PLANET MARS

The Martian crust is the outer solid layer of the planet, mostly basaltic. It is rich in silicates, oxygen, iron, magnesium, etc. Estimates of the thickness of the crust vary from 10 to 47 km. Unlike Earth, which has moving lithospheric plates, the Martian crust is the only relatively immobile global plate. Beneath the crust is the mantle. It probably consists of a single thick layer, consisting mainly of silicate rocks rich in magnesium and iron. In the center of Mars is a metallic core with a radius of 1630-1860 km and a density of 6.2-6.3 g/cm2. At least the outer part of the Martian core is in a liquid, molten state, and in the middle is a solid inner core.
