About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...

Seismic waves generated in Earth's interior provide images that help us to better understand the pattern of mantle convection that drives plate motions. You have full access to this article via your ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a | Earth And The Environment ...

Scientists looked into decades of seismic wave data and found that it behaved differently in distinct parts of the cores.

In the absence of a 6,000 km-deep hole to conduct observations, scientists hoping to learn about the internal structure of the Earth presently have few options but to monitor seismic waves. However, ...

Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, ...
