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

Pranjal Malewar

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.

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.
