Temporal evolution for the viscosity (upper row) and compositional (lower row) field of the 3D reference case showing LLSVP-sourced plume-induced subduction initiation. (a–) Model snapshots at 0 Myr ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Carole ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

Scientists have discovered a long hidden plate boundary near the east coast of Africa that dates back about 180 million years ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

Europe and Canada may one day smash into each other if dramatic new research is to be believed. Scientists say one of Earth’s tectonic plates, the massive shelves of crust that carry the continents ...

Make sure you pencil this into your long-term calendar, estimates place the death of plate tectonics here on Earth at 1.45 billion years from now. The existence of plate tectonics on Earth makes it ...
