On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic core of our planet. The mantle is ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

Scientists have uncovered potential remnants of Earth's ancient crust, often referred to as ‘sunken worlds,’ hidden deep within the mantle.And this was possible because of a new way of mapping ...
