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.
The lithosphere is the solid and rigid outer layer of our planet. It includes the crust and part of the upper mantle that contains rigid rocks.Beneath this layer is the asthenosphere where the rocks in this part of the upper mantle are not rigid.The rocks can flow like a liquid or break apart similar to silly putty.ithosphere. Introduction. The lithosphere is the solid and rigid outer layer of our planet. It includes the crust and part of the upper mantle that contains rigid rocks. Beneath this layer is the asthenosphere where the rocks in this part of the upper mantle are not rigid.
