New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead ...

The two giant blobs — one beneath the Pacific Ocean and one beneath Africa ... shows how tectonic plates dive into the mantle, while mantle plumes fed by LLSVPs bring deep mantle material ...

It is found in the depths of Indian Ocean and named as the gravity hole or Indian Ocean geoid low, an anomaly where gravity ...

Mantle dynamics drive the formation of ocean islands and seamounts in the interior of oceanic plates. Yet the mechanisms for generating these volcanic edifices differ from chain to chain ...

Over 25 years ago, researchers discovered that some of these deep Earth reverberations pointed to the existence of two underground “super-continents” hundreds of miles beneath Africa and the Pacific ...

Close to the summit of an underwater mountain west of the Mid-Atlantic Ridge, a jagged landscape of towers rises from the ...

These are common in the Pacific Ocean; Hawai'i is a famous example. They form from large blobs of rock that slowly rise from ...

This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath ... between seismically-slow "plumes" and channels imaged in the study. Green cones on the ocean floor mark islands ...

The mantle, by contrast, was seen as little more than a thick layer of hot rock, with the occasional plume pushing its way through. Now, the team on this new effort reports that a lot more is ...

The Indian Ocean "gravity hole ... the presence of low-density magma plumes beneath the gravity hole, which could confirm the model’s predictions about mantle activity. Earth’s Hidden Blobs ...
