Magnetic field mantle convection
Web14 jun. 2024 · Convection occurs when heavy metals solidify in the inner core, while lighter metals are displaced to the outer core. The rotation of the Earth and convective motion produces the appropriate motion that is conducted to the surface and into space. WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid …
