On the diagram below: draw the three major divisions of the Earth (include depths in km) add any major subdivisions list the dominant minerals or chemical elements that comprise each division include the Moho Where is the crust the thickest? Where is the crust the thinnest? What has the greater density, inner core or outer core? Why? What is the dominant mineral structure of the

Explanation / Answer

a) & b) The answers for the questions a and b are done by you. So let me answer the remaining.

c) The crust is composed majorly of sial (Granitic rocks) and sima (Basaltic rocks), The mantle is composed of high Mg and Fe content ( Eclogite, Peridotite, Dunite, Hartzburgite) and the core compose of high densar Ni and Fe elements.

d) The mohorovicic discontinuity is placed between crust and mantle.

The earth crust is thickest at mountain regions.

The earth crust is thinnest at oceanic regions.

The outer core has highest density about 12.6 to 13.

Because the inner core is in the form of solid state and the outer core is in liquid state.

2. The mantle is a maffic silicate rocky shell generally composed of olivine and pyroxene minerals rich.
