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 the lower portion of the Earth's mantle. Its  temperature ranges from 1000 degrees Celsius to 2500 degrees  Celsius.he asthenosphere is a physical layer of the upper mantle which is directly below the lithosphere. The asthenosphere is composed of ultramafic rock and is believed to be rough â¦ ly 5% molten. The lithosphere, which includes the continental and oceanic plates, floats on the plastic-like asthenosphere.
