Distinguish between Sial and Sima KnowledgeBoat

The sima has a higher density (2800 to 3300 kg/m ) than the sial, which is due to larger amounts of iron and magnesium, and smaller amounts of aluminium. When the denser sima comes to the surface it forms mafic rocks, or rocks with mafic minerals. The most dense sima has less silica and forms ultramafic rocks. WebThe portion of the interior beyond the crust is called the mantle. It is in a solid-state. It has a density higher than the crust portion. The thickness ranges from 10-200 km.
