A double subduction zone off Japan fueled the formation of some of North America's most iconic features.

Plate tectonics is the means through which mountains are formed. The Baird Mountains in Alaska's Kobuk Valley National Park formed when two tectonic plates along a convergent boundary collided, ...

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 ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

Subduction zones are cornerstone components of plate tectonics, with one plate sliding beneath another back into Earth's mantle. But the very beginning of this process—subduction initiation—remains ...

WASHINGTON — A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU ...

Venus and Earth are similar in size and mass, but took strikingly different evolutionary paths. After all, Earth is – at present – an oasis for life. And Venus, the planet next door, is a boiling ...
