Earth's Layers (The internal structure of the Earth) Earth’s Layers (Kelvinsong, from Wikimedia Commons) The interior of the earth is made up of several concentric layers of which the crust, the mantle, the outer core and the inner core are significant because of their unique physical and chemical properties. The layer next to it is SIMA makeup of silica and magnesium and an average thickness of this layer is 100 to 2900 km. Sima is the layer that makes up the ocean floor. sial (English) Alternative forms. The lower part of the crust. asked Jan 26 in Geography by Raju01 (58.2k points) Expand SIAL and SIMA.

Q5. smartynaira29 smartynaira29 18.05.2019 Social Sciences Secondary School +5 pts. Sial (silicate and aluminium) is the name of crust under the seas and oceans. The average density of SIMA is 2g per cubic cm. Answer: It is made up of Silica (Si) and Aluminium (Al). It is the inner layer of the crust which is separated from sial layer by the zone called Conrad discontinuity line. (a) Seismic waves (b) Gravitational force (c) Volcano (d) Magnetism of the Earth Answer: (c) Volcano. SIAL, comprising the continents, is floating over SIMA, which is the upper portion of the seafloor. The average thickness is 8 to 100 km. nife -(ni-nickle and fe-ferrous).the innermost layer is the core with a radius of about 3500km is mainly made of nife. The upper part of the earth’s crust. What are intrusive igneous rocks and extrusive igneous rocks? Hence it is named as SIAL. (a) By Van der Gracht (b) By Dely (c) By Homes (d) By Suess See also . nife (uncountable) nickel–iron, especially the material that makes up the core of the Earth; See also . The inner core is in the solid-state whereas the outer core is in the liquid state. The inner layer again has three layers, i.e, SIAL which is made of silica and aluminum.
