A plume of molten rock rising from the depths of the Earth in heartbeat-like pulses is slowly tearing Africa apart—and will one day create a new ocean. This is the conclusion of an international team ...

The chemicals inside that little blob suggest so-called plate tectonics revved up during the first billion years of Earth's existence. Since the 1950s, scientists have known Earth's crust is made ...

Magma: hot stuff, coming through. A better understanding of the movement of magma at plate boundaries could help predict volcanic eruptions more accurately, ... beneath another plate. Tectonic plates ...

Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones meet in East Africa ...

When Earth was young and hot, during the Hadean eon (4.6 billion to 4 billion years ago), the planet was first covered with a magma ocean and then, as the planet cooled, a solid rock surface.

Towards A Better Understanding Of Hot Spot Volcanism Date: February 4, 2008 Source: Institut de Recherche Pour le Développement Summary: Researchers investigated the phenomena that led to the ...

Hot block. Simulations of Yellowstone’s underbelly suggest that the relatively cold remnants of an ancient tectonic plate (blue) block the heat from a rising mantle plume (red) from reaching the ...

Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate Date: June 20, 2023 Source: Georgia Institute of Technology Summary: A team of scientists has observed past episodic ...

The mantle, though not as hot as the earth’s core, is hot enough that some rocks start to melt. This molten rock, called magma, is less dense than the surrounding rocks in the mantle. Due to this ...

Enough hot rock sits beneath Yellowstone National Park to fill the Grand Canyon nearly 14 times over, according to our best view yet of the supervolcano that lies below the famous landscape.
