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 ...

We finally know where two giant blobs in Earth's middle layer came from — and they're a mismatched pair. These strange regions in Earth's mantle, known as "large low velocity provinces" (LLVPs), are ...

It is unlikely that the Earth's mantle — the layer beneath ... Although such a 'plum-pudding' mantle — one consisting of blobs of one composition dispersed in a matrix of another — has ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

The discovery bolsters the theory that meteorite impacts played an important role in Earth's early geological history ...

Massive mantle formations, called LLSVPs, have been found to be over a billion years old. These structures, sitting 3,000 km beneath the surface, slow seismic waves, indicating unique physical and ...

The Earth is made up of different layers ... Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and ...

One theory suggests superplumes could be leftovers from Theia, the Mars-sized protoplanet that formed the Moon after colliding with Earth. Dangerous emoji meanings exposed: Are your kids using ...

School children learn about the make-up of the Earth with an image depicting the Earth's core, mantle and crust layered ... make-up of some continental-sized blobs deep inside the Earth.

Others have suggested that the blobs are huge chunks of oceanic crust that were pushed into the mantle when one tectonic plate slipped under another — a process known as subduction. The crust ...
