They found an odd ring around the outer core's equator, where earthquake waves move more slowly than in surrounding regions. Earth's outer core is made up of liquid iron and nickel and surrounds ...

Researchers discovered a donut-shaped region at the ceiling of the outer core This lighter region helps stir the liquid metal which generates the magnetic field Scientists have uncovered a vast ...

A terrifying simulation has shown exactly what would happen if the Earth's core drastically dropped in temperature. While it's unlikely to occur in our lifetimes, the centre of our planet cooling down ...

In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...

A sphere of solid iron-nickel about 3,000 miles below the surface, Earth’s inner core is about the same size as the moon and surrounded by an outer core of liquid iron-nickel outer core.

Prior research has shown that Earth's inner core is essentially a hot, metal ball. The outer core, beneath the mantle, is believed to be made of a colder liquid metal. Since both spin, the result ...

Tectonic plates float on the semi-solid mantle, 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 ...

Its temperatures can reach 5500°C. Outer core The outer core is the layer surrounding the inner core. It is made of liquid iron. Mantle The mantle is the layer of the Earth which makes up 84% of ...
