WebTectonic Plate Boundaries The outermost shell of the Earth consists of a mosaic of rigid “plates” that have been moving relative to one another for hundreds of millions of years. … The outer layers of Earth are divided into the lithosphere and asthenosphere. The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confus… iowa wesleyan college jobs https://iaclean.com
