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 ...

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 ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

Research led by Jesse Reimink, assistant professor of geosciences at Penn State, suggests that the Earth's crust continued a slow process of reworking for billions of years, rather than rapidly ...

Computational modeling shows that plate tectonics weren't necessary for early continents. The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists ...

BUFFALO, N.Y. — At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from ...

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 in the open access journal AGU ...

Researchers have examined tiny time capsules found in the oldest-known crystals in an attempt to settle a question that divides scientists: when did Earth’s tectonic plates begin to move? Plate ...

A new study from Harvard geoscientists reports the oldest direct evidence yet of plate motion, dating to 3.5 billion years ago. In a study published March 19 in Science, the researchers found that ...

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 ...

At the boundaries between tectonic plates, narrow rifts can form as Earth's crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force ...
