Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's surface. The mantle contains both magma, or molten rock, and slowly-moving solid rock. Earth's innermost layer is ...

The Earth is made up of different layers. The outermost is the crust, which is where we humans stand. The next layer is the mantle, which makes up most of Earth's volume and is composed of dense ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.
