Magma in mantle has deep impact: Study suggests rocks melt at a greater depth than once thought
Magma forms far deeper than geologists previously thought, according to new research at Rice University.
Dinosaur die-out might have been second of two closely timed extinctions
The most-studied mass extinction in Earth history happened 65 million years ago and is widely thought to have wiped out the dinosaurs. New University of Washington research indicates that a separate extinction ...
New model suggests ocean pH falling more rapidly
Bacteria alive (more or less) in 86-million-year-old seabed clay
Thawing permafrost 50 million years ago led to extreme global warming events
In a new study reported in Nature, climate scientist Rob DeConto of the University of Massachusetts Amherst and colleagues elsewhere propose a simple new mechanism to explain the source of carbon that fed a ...
New exploration shows parts of North Atlantic seabed were once above sea level
Unusual earthquake gave Japan tsunami extra punch
The magnitude 9 earthquake and resulting tsunami that struck Japan on March 11 were like a one-two punch first violently shaking, then swamping the islands causing tens of thousands of deaths ...
Geophysicists claim conventional understanding of Earth's deep water cycle needs revision
A popular view among geophysicists is that large amounts of water are carried from the oceans to the deep mantle in "subduction zones," which are boundaries where the Earth's crustal plates converge, with ...
Triple whammy triggered Samoa tsunami (Update 2)
A tsunami that hit the Pacific islands of Samoa and Tonga last year was generated by three earthquakes unleashed by a seismic mechanism that has never been observed before, scientists said on Wednesday.
Small fish exploits forbidding environment
Jellyfish moved into the oceans off the coast of southwest Africa when the sardine population crashed. Now another small fish is living in the oxygen-depleted zone part-time and turning the once ecologically ...
New insights into volcanic activity on the ocean floor
New research reveals that when two parts of the Earth's crust break apart, this does not always cause massive volcanic eruptions. The study, published today in the journal Nature, explains why some parts ...
Arctic ice at low point compared to recent geologic history
Less ice covers the Arctic today than at any time in recent geologic history. That's the conclusion of an international group of researchers, who have compiled the first comprehensive history of Arctic ice.
China looks to 'combustible ice' as a fuel source
Earth's early ocean cooled more than a billion years earlier than thought (w/ Video)
(PhysOrg.com) -- The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 ...
