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 ...

A hidden structure that is 5000 degrees and moving was discovered inside the Earth's core. What do the past, present and ...

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 ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge ...

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 ...

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

This broad, 8,000-mile-long bulge in the crust of the earth differs in many ways from the rest of the ocean bottom. It may be the result of huge convection currents in the interior By Henry W. Menard ...

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 ...
