the upper mantle and the lower mantle. The boundary between the two lies about 465 miles (750 kilometers) beneath the Earth's surface. The crust is the outermost layer of the Earth. It is the ...

Like straight out of Julio Verne's Journey to the Center of the Earth, scientists from Northwestern University and the ...

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

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

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer.

These reactions transform the mineral olivine — predominant in the upper layer of the Earth’s mantle — into serpentine rocks, ...

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 ...

"Our new results suggest that for most of Earth's history, convection in the mantle was stratified into two distinct layers, namely upper and lower mantle regions that were isolated from each ...

"The small deformation rates indicate that the upper mantle of Mars is cold, highly viscous and much stiffer than Earth's upper mantle," she said. So how can measurements of ice weighing down ...

(b) Schematic diagram of the upper mantle structure beneath the Tonga-Lau-Fiji region. A landmark study published in Geoscience—a leading Chinese journal at the forefront of earth science ...

Mars's upper mantle is stiff, with a viscosity 10 to 100 times higher than Earth's. Focus: Planetary research, Mars, space To understand the properties of the rocky mantle beneath Earth's continents, ...
