A profession needs extensive training and specialized knowledge. On the other hand, an occupation does not need any extensive training.
1. One of the confusing concepts of Earth structure is the distinction between chemical layering (crust, mantle and core) and mechanical layering (lithosphere, asthenosphere and mesosphere). The scale model illustrates all of these layers on a single diagram.ne of the confusing concepts of Earth structure is the distinction between chemical layering (crust, mantle and core) and mechanical layering (lithosphere, asthenosphere and mesosphere). The scale model illustrates all of these layers on a single diagram.
Is the asthenosphere made of iron and nickel? No, the iron and nickel are to be found much deeper in the core of the Earth. The asthenosphere is the mechanically weak, ductily-deforming region of the upper mantle of the E â¦ arth. It lies below the lithosphere, at depths between 100 and 200 km.
