What is Mars Made Of? - WorldAtlas
Unlike the Earth''s mantle that is solid, the mantle of Mars consists of soft rocks. The mantle is between 770 and 1,170 miles thick. Mars has a solid core that is between 930 and 1,300 miles in diameter.The core is dormant and therefore lacks a magnetic field that protects the planet from space radiation.
