WebNov 9, 2024 · Most terrestrial planets possess a core composed of a solid inner core and a liquid outer core. Flow of liquid in the outer core results in the generation of an internal magnetic field on terrestrial bodies [].A major energy source of fluid motion is thermal convection which is active when thermal conduction, or outer core adiabatic heat flow, … WebMar 1, 2024 · Mantle convection describes the movement of the mantle as it transfers heat from the white-hot core to the brittle lithosphere. The mantle is heated from below, cooled from above, and its overall temperature decreases over long periods of time. All these elements contribute to mantle convection. howard university dental hygiene
