However, scientists have been baffled to discover that the inner core is actually changing shape. By looking at the ...

Data collected by NASA's InSight lander suggest that ancient internal processes are responsible for the "Martian dichotomy" ...

"These two large islands are surrounded by a graveyard of tectonic plates that have been transported there by a process ...

Earth has a lot going on under the surface - even in what may have once seemed to be its most unassuming layer.

Understanding plate tectonics is key to grasping how the Earth’s geology works and how oceans and continents came to be. These massive slabs, part of the lithosphere, meet at their edges where all the ...

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for ...

These movements, called convection, are responsible for plate tectonics. Oceanic plates, being denser, plunge into the mantle at subduction zones, while hot material rises to the surface. This cycle ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds.

But it does – and the Tesla Model 3 is the best known. It is, famously, a fully electric car – Tesla doesn’t do petrols, diesels or even hybrids – and it’s the US brand’s smallest and ...

These unexpected regions of the Earth's innards appear to be hotter and older than other structures nearby that are known to be sunken tectonic plates, possibly being around 500 million years old ...
