When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on ...

However, this explanation also raises problems. Rapa Nui is thought to be the product of a mantle plume, a giant column of ...

Lava that erupts from hotspots around the world seems to come from a similar ancestral magma, new research finds.

They form from large blobs of rock that slowly rise from the deep Earth's mantle—so-called mantle plumes. When they get close to the base of the Earth's plates, the rocks of the plume as well as ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Geologists studying Easter Island recently opened up another mystery centered around the famous region. A team from Colombia’s Universidad de Los Andes, led by Cuban geologist Yamirka Rojas-Agramonte, ...

They form from large blobs of rock that slowly rise from the deep Earth's mantle -- so-called mantle plumes. When they get close to the base of the Earth's plates, the rocks of the plume as well ...

These volcanoes form when plumes of hot rock rise slowly from deep in the Earth’s mantle and melt as they near the crust, creating volcanic activity. The Hawaiian Islands, for example, are the result ...

Rapa Nui is thought to be the product of a mantle plume, a giant column of hot molten rock that allows material to move from deep within Earth's mantle to the surface. It’s believed that mantle ...
