WebQ. The upper layer of the mantle is said to be thicker than the lower mantle, but not solid rock like crust. The tectonic plates rest on this layer and it is responsible for the movement of those plates. What is the name of this layer? Q. The innermost layer of the Earth is thought to be made of solid iron. Webregion shows mantle that has intruded upwards (e.g. volcanism, geothermal vents). The horizontal thin line at 1 bar is the average sea level atmospheric pressure of the Earth. The parameters of our Earth model (e.g. core, mantle, continental crust, oceanic crust, geotherms and atmospheric lapse rates) are given in Appendix A of JL10.
