THE STRUCTURE OF THE EARTH Introduction: Earth cosist of internal and external structure. Internal structure consist of three layers namely CRUST,MATLE and CORE. Crust is the outer most layer of the earth which consist of SIAL and SIMA. sial contains silca + aluminium, and Sima contains silca + magnesium. MATLE is a second layer of the earth or mantle is the interior part of the earth lying between crust and core. The layer which separates crust from mantle is called MOHOROVIC DISCONTINUITY. The third or last part of the internal structure of the earth is CORE or CORE is a central part of the earth's interior and made up of two minerals which are nickel and iron.core is divided into two zones which are BARYSPHERE (outer zone) and CENTROSHERE (Inner zone). The layer which separates core from Matle is called GUTENSBURG DISCONTINUITY. Summarised by suhaila (me)
