We can’t get samples from either of them, so these conclusions are based on models of the way convection drives circulation within the mantle. The team thinks the fact the two LLVPs are on almost ...

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

Therefore, they do not take part in mantle convection (the flow in the Earth's mantle). Thus, contrary to what the geography books teach us, the mantle cannot be well-mixed either. Talavera-Soza ...

This movement is driven by the very slow creeping motion of Earth's mantle, called convection, which carry heat from the interior to our planet's surface. Researchers believe that convection in ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

It is unlikely that the Earth's mantle — the layer beneath the crust and above the core — was completely homogeneous when it initially formed. Over time, cooling-induced convection as well as ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

Whether convection in the Earth's mantle extends through its entire depth or if the mantle is layered has long been debated. Recent research suggests that spatially and temporally intermittent or ...

The Earth is made up of different ... it is the plates that drive the convection. Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones.

Beneath the Indian Ocean lies a 106-meter gravity hole, caused by ancient mantle plumes and vanished oceans. Scientists trace ...

Despite having been studied from every possible point of view and angle, the Earth will remain a mystery to most people. Studies of its structure are incomplete, especially after t ...
