blue path illustrates a core-penetrating seismic wave

Seismic wave data revealed changes in the Earth’s outer core

Scientists have never directly observed convective flows or how they may be changing.

The blue path illustrates a core-penetrating seismic wave moving through a region in the outer core, where the seismic speed has increased because a low-density flow has moved into the region.

Understanding changes in Earth’s outer core with the help of seismic waves

The composition of the bulk, the outer core of the Earth, is not pure iron but has a density deficit of about 5–10%, indicating...

New tectonic plate model

How the Earth’s continents were assembled?

Updating our understanding of Earth’s architecture.

Creative destruction: a thinner ocean plate sides under a continental plate, melting and recycling the ocean crust into the Earth’s interior and birthing volcanoes in this illustration of subduction, a consequence of modern plate tectonics. A new study reports evidence of a transition in multiple locations around the world, 3.8-3.6 billion years ago, from stable “protocrust” to pressures and processes that look a lot like modern subduction, suggesting a time when plates first got moving.
