Given that all of the Hawaiian Islands were created by volcanic activity, it is somewhat surprising that only one of the islands possesses any active volcanoes. Why did the volcanoes that built the ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

Plate tectonics, responsible for deadly earthquakes and volcanoes around the globe, may also be a key factor in the success of life as we know it on the third planet, a new study suggests. As the ...

Plate tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomenon. The rigid lithosphere is split into 15 major plates that slowly move on top of ...

Geophysicists point to a super-hot layer beneath the tectonic plates as the place of origin for volcanoes, as opposed to deep within the Earth's core. A long-held assumption about the Earth is ...

A 2,500 km long line of volcanoes, with 80 volcanic mountains and 41 historically active (since 1760 AD) volcanoes produce an arc stretching along the southern edge of the Bering Sea and onto the ...

A tectonic plate "lost" for 60 million years under the Pacific Ocean has been reconstructed by scientists at the University of Houston. Known as Resurrection, the plate has been a controversial topic ...

Some mountains in "mobile belts" -- regions of crustal fragments, such as in the Mediterranean, the Rockies, and the Himalayas -- can rise due to upward pressure from the semi-liquid mantle. The study ...
