Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

Our planet has been asteroid-smashed, melted and eroded, enough that most of its original armor has been long buried. Except ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate ...

Researchers mapped a pulsing mantle plume under Afar that channels molten rock upward, stretching Africa’s crust until it ...

Geographic (A) and tectonic (B) maps of the Philippine Sea Plate region. Present-day plate boundaries are red (modified from Bird, 2003), relevant former plate boundaries are gray.

During this tectonic movement, plates are neither formed nor destroyed. At a transform plate boundary, the two plates’ relative motion is either sinistral (left side toward the observer) or ...

“By simulating how the Earth's tectonic plates are expected to evolve using a supercomputer, we were able to show that in less than 300 million years' time it is likely to be the Pacific Ocean ...

Whether that new divide counts as a boundary or not, the Pacific Plate is still the largest of all tectonic plates. It measures 39,768,522 square miles (103,000,000 square kilometers) in size, and ...
