Sial is lighter than sima, and it is floating over sima as suggested by many geomorphologists. It is made up of dense layer very rich in olivine. It is safe to assume that Mantle is called Fema (Iron and Magnesium) as Mantle is composed of silicate rocks that are rich in iron and magnesium. The core-mantle boundary is positioned at the depth of 2,900 km. Has granite rocks and forms continents. The name Sial is based on the excess of Silica and Aluminium.

Interior of the Earth was divided into the form of Sial, Sima and Nife. The sial is made up of silica and aluminum while Sima has an abundance of silica and magnesium. This layer lies below SIMA. The oceanic crust mainly consists of silica and magnesium; it is therefore called sima (si-silica and ma-magnesium) Q32. Hence it is called SIMA. Geomorphology multiple choice questions and answers e.g. Question 6. the oceanic crust mainly consist of sima. MANTLE ; Mesosphere or mantle is found between the crust and core. Answer.
