Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...
Scientists have identified two enormous mountains hidden deep beneath the Earth’s surface, each standing an extraordinary 620 miles (1,000 kilometers) tall—more than 100 times taller than Mount ...
Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...
That part of the mantle is made of old tectonic plates that break into tiny pieces when they sink deep enough into the planet. The LLSVPs, by contrast, contain larger crystals than their surroundings.
Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.
The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...
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 last ice age provides insights into Earth's mantle dynamics The surfaces of Earth and other rocky planets may appear proverbially 'rock solid', but events such as volcanic eruptions and ...
