An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

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 ...

On Earth, the land moves. Over millions of years, continents shift and the entire surface of the planet reshapes itself. The driver of all this is plate tectonics: Earth’s surface is divided into ...

Plate tectonics is a key geological process operating on Earth, shaping its surface, strongly influencing its deep structure and making it unique among the rocky planets in the Solar System. How plate ...
