The only explanation then is that the ancient minerals originated at the source of volcanism, in the Earth's mantle beneath the plate, long before the formation of today's volcanoes. But that ...

In the middle of the Pacific Ocean, thousands of miles from any continent, Easter Island rises out of the sea. Its surface ...

The Jwaneng Diamond Mine, located in Botswana, is the richest diamond mine globally, with an estimated value of 1 billion ...

The Aral Sea's disappearance displaced 1.1 billion tons of water, causing Earth’s mantle to rise. A silent, human-made shift ...

More information: Aaron J Pietruszka et al, Awakening of Maunaloa Linked to Melt Shared from Kīlauea's Mantle Source, Journal of Petrology (2024). DOI: 10.1093/petrology/egae121 Provided by ...

Furthermore, the findings bolster the theory that the moon formed when a giant, Mars -size protoplanet slammed into the young ...

Venus, the hottest planet in the solar system, is estimated to have 85,000 volcanoes, based on radar images from NASA's 1989 Magellan mission. Now, scientists have a new theory about what fuels the ...

Future missions to Venus could also supply additional data on the density and temperature of the planet's crust, which could be used to test the researchers' hypothesis. If crustal convection is ...

But since Mount Spurr is showing signs of unrest, the quake may be linked to magma rising from deeper in the mantle. Scientists at the Alaska Volcano Observatory (AVO) have warned that Mount Spurr is ...

A magma hotspot is a localized area in Earth's mantle where unusually hot rock rises toward the surface, causing volcanic activity. Unlike volcanoes at tectonic plate boundaries, hotspots occur in ...

Venus may be far more geologically alive than anyone expected. New research suggests its outer crust could be churning with convection, a process that helps move heat and may explain the planet’s tens ...

On Earth, convection deep in the mantle provides the energy that drives ... Surface temperatures reach 870°F, and its volcanoes and other surface features show clear signs of melting.
