Another difference that can be seen between profession and occupation, is that the former is guided through certain ethical codes, and is regulated by a certain statute. Summary: 1. 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 asthenosphere is a weaker layer that flows right underneath the lithosphere. Together, the lithosphere and the asthenosphere comprise what scientists refer to as the earthâs mantle.There are two different kinds of lithosphere which together make up the earthâs surface, or crust. The oceanic lithosphere is essentially what is referred to as the ocean floor.he asthenosphere is a weaker layer that flows right underneath the lithosphere. Together, the lithosphere and the asthenosphere comprise what scientists refer to as the earthâs mantle.
