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 ...

Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

Computer simulations suggest that a collision with another planetary object early in Earth’s history may have provided the heat to set off plate tectonics. By Lucas Joel Some 4.5 billion years ago, ...

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants can ...

The tectonic plates are among the most powerful forces on Earth, exerting tremendous influence over every single life that unfolds on this planet. They are both creators and destroyers, capable of ...
