Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

Deadliest volcanic eruption: The 1815 eruption of Mount Tambora in Indonesia, which killed up to 100,000 people From lava fountains to towering ash clouds, volcanoes produce some of the most dramatic ...

A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists have recently discovered. Their new model takes into account not only the velocity of ...

Map of Earth's principal tectonic plates. Earth's lithosphere. Major and minor plates. arrows indicate direction of movement at plate boundaries. Vector illustration. Billions of years ago, Earth's ...

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 ...

Based on a series of models considering how the continents were assembled over time, a team of researchers at the University of Adelaide created an updated map of Earth's tectonic plates. The map will ...

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 geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...

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 ...
