Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy. The ...

In 2021, geologists animated a video that shows how Earth's tectonic plates moved over the last billion years. The plates move together and apart at the speed of fingernail growth, and the video ...

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 ...

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...

This groundbreaking research offers a comprehensive reconstruction of Earth’s tectonic evolution from 1.8 Ga to the present, bridging critical gaps in pre-Pangean plate dynamics. By merging three ...

Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. PROVIDENCE, R ...

Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate ...

The Salton Sea is located in a sedimentary basin at the southern termination of the San Andreas fault. High-resolution seismic data indicate that the basin formed and grew by active subsidence at its ...

From space, the Iberian Peninsula – primarily occupied by Spain and Portugal – looks like an immovable solid block of land anchoring southwestern Europe. But beneath that apparent stability, the ...

Scientists have reconstructed a long-lost tectonic plate that may have given rise to an arc of volcanoes in the Pacific Ocean 60 million years ago. The plate, dubbed Resurrection, has long been ...
