Earth's outer core has a radius of around 2,160 miles (3,480km) - making it slightly larger than Mars. Mainly made of hot nickel and iron, convection currents coupled with the Earth's rotation ...

When an electric current passes ... (High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the ...

Electrically charged, liquid iron flows around the solid inner core driven by Earth's rotation and convection currents. These movements produce electric currents, which, in turn, generate the ...

which moves very slowly as a result of convection currents driven by heat energy from the hot core. The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner ...

As the hot current nears the crust, it begins to cool and sink back towards the core. As the magma sinks, it drags the plates across the surface of the Earth. Where convection currents push plates ...
