Question 2(multiple choice worth 3 points) which of the following is most dense? asthenosphere continental crust core o mantle oceanic crust

Mantle oceanic crust

Explanation:

The Asthenosphere consists of heavier elements like aluminum, magnesium basaltic rocks and made up of old oceanic plates. This liquid layer is based on deformation properties. Which are later characterized by Isostatic adjustment? Due to high temperature and pressure conditions in this layer the rock is in the molten state. Plates above move in n ductile manner as the oceanic crust has a density of  3.0 g/cm cube, and that of continental crust is about 2.83 g/cm cube.  Thus lighter plates or continents can move on this layer as they are less dense and hence they, later on, move back into the same oceanic trenches through the process of subduction.

The answer i think is d
