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

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The new study reveals that the African plate and the Pacific plate have different chemical compositions and ages, parting ways with the old study, which proposed they are both similar in composition.

Continent-size islands deep inside Earth's mantle ... LLSVPs and the surrounding mantle. From these data, the researchers calculated both the speed of the seismic waves and how quickly they ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

Well, the verdict is in. The Moon is not made of green cheese after all.

Understanding the inner core’s behavior helps scientists better grasp these fundamental planetary processes. For nearly three decades, scientists have used seismic waves from earthquakes to ...

Two massive structures are located inside Earth - under the Pacific Ocean and beneath Africa and parts of the Atlantic. No ...
