SpletYes. Earth's main cooling system is called Meridional Transport (MT), which constantly moves heat from the Tropics to the Poles -- via air and oceans currents. But, warm sunny ocean currents (like Gulf Stream) ride in the upper layers. The lower layers are heated by volcanism. 14 Apr 2024 14:36:33 The structure of Earth can be defined in two ways: by mechanical properties such as rheology, or chemically. Mechanically, it can be divided into lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core. Chemically, Earth can be divided into the crust, upper mantle, lower mantle, outer core, and inner core. The geologic component layers of Earth are at increasing depths be…

Spletlithosphere. the solid rock layer of the Earth that includes the crust and the uppermost part of the mantle, broken up sections form Earth's tectonic plates. asthenosphere. the mantle layer of semi-solid rock that flows with convection currents beneath the lithosphere. It has the property of "plasticity", like oobleck or slime.
SpletTherefore, the layering of Earth is a result of gravitational pull. The densest layer (inner core) is at the center and the least dense layer (crust) is the outermost layer. The atmosphere, composed of gases, can technically be considered a layer as well and is obviously lighter than the crust.
