Layer Name Crust Location Description The ground we stand on is part of the core. It is the outer-most layer of the geosphere. Made up of mostly rock, soil formation takes place here, temperature and pressure increase as you go closer to the center of the Earth Just below the crust, it is a very thick layer of the Earth. Made up of very hot solid rock, convection currents occur here (heat is transferred from the center of the Earth to the surface through the mantle) PL E Image Mantle Mantle = Middle AM The core is at the very center of the Earth. Core The outer core is made up of mostly metal. This metal is so hot that it is liquefied. In the inner core, the pressure is so great that the metal remains solid. The center of the Earth is the most dense point of the Earth. Explain each method of heat transfer. EX Radiation: When heat is transferred through the use of waves of energy___________________ Convection: When heat is transferred through the use of a gas or liquid____________________ Conduction: When heat is directly transferred from one object to another__________________ Which form of heat transfer is found in the mantle? Explain. Convection. As heated pieces of the mantle rise, that heat is transferred toward the surface. When the heated mantle cools, it sinks back down toward the core forming a cycle.__________
