Facts about Mantle talk about a layer, which can be found on earth and other terrestrial planets. The location of mantle is around the core of earth. The formation of mantle will take place as long as the planetary body is big enough. The terrestrial planets, which have mantle, include Mercury, Mars, Venus and earth. The mantle created from silicate rock is spotted on Vesta, Europa and lo. Other astronomical bodies like Triton, Titan, Callisto and Ganymede are reported to have a mantle created from ice. Let us get other interesting facts about mantle below:

Facts about Mantle 1: the mechanical properties

The composition of mantle and crust is different. Therefore, the mechanical properties of both are also different.

Facts about Mantle 2: the differences of mantle and crust

The seismic characteristics, rheology, rock types and chemistry are the factors, which differentiate the crust and mantle.

Facts about Mantle 3: the mantle rocks

The magnesium to iron ratio is higher in typical mantle rocks. On the other hand, the crust has smaller amount of aluminum and silicon.

Facts about Mantle 4: the components of mantle rocks

Garnet, spinel-structure minerals, pyroxenes and olivine are the components of mantle rocks located with the depth shallower than 250 miles or 410 kilometers.
