This mantle is made up of silicates. If the planetâs core is liquid then its mantle is closer to the consistency of soft rock paste that is less dense than its core. This mantle is then covered by a crust which can vary in terms of thickness from 50 km to 125 km.This is comparably thicker than the Earthâs own crust which averages 40 km.nown as the red planet, Mars is nearly half the size of the Earth. Its outer surface is composed of mostly basalt that was brought to the surface by ancient volcanoes, which were active during the planetâs early history.
