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).

Answers. Best Answer: The lithosphere consists of the heavy oceanic and lighter continental crusts, and the uppermost portion of the mantle. The asthenosphere is the region in the upper mantle characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere.nswers.
