Mountain-building process much faster - and cooler - than previously thought, say Queen's geologists
Geologists at Queen's University have discovered that the time it takes for mountain ranges to form is millions of years shorter than previously thought. view more (2005-07-01)
The kapok connection -- Study explains rainforest similarities
Celebrated in Buddhist temples and cultivated for its wood and cottony fibers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago. view more (2007-06-18)
Earth's heat adds to climate change to melt Greenland ice
Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. view more (2007-12-13)
Half-baked asteroids have Earth-like crust
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. view more (2009-01-08)
Seismologists see Earth's interior as interplay between temperature, pressure and chemistry
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse. view more (2007-10-26)
'Roof of the world' tells tale of colliding continents, Earth's interior
Geologists have learned that the height of the Tibetan Plateau, a vast, elevated region of central Asia sometimes called "the roof of the world," has remained remarkably constant for at least 35 million years. view more (2006-02-09)
Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. view more (2005-08-09)
Banded rocks reveal early Earth conditions, changes
The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. view more (2009-10-12)
FSU geochemist challenges key theory regarding Earth's formation
Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes that helped shape the Earth as we know it today. view more (2008-05-01)
UCLA engineering researchers capture optical 'rogue waves'
Maritime folklore tells tales of giant "rogue waves" that can appear and disappear without warning in the open ocean. Also known as "freak waves," these ominous monsters have been described by mariners for ages and have even appeared prominently in many legendary literary works, from Homer's "Odyssey" to... view more...

Earth's Moving Crust May Occasionally Stop
The motion, formation, and recycling of Earth's crust-commonly known as plate tectonics-have long been thought to be continuous processes. But new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth's geologic history, and may do so again. The findings could reshape our understanding of the history and... view more... (2008-01-10)
UCL scientists create first earthquakes in the laboratory
Scientists at UCL have recreated earthquakes in the laboratory for the first time allowing them to better understand the origin of the largest and most violent earthquakes. This is the first time scientists have been able to generate and observe deep and intermediate focus earthquakes in the laboratory, recreating the exact pressure and... view more... (2002-11-14)
Solomon Islands earthquake sheds light on enhanced tsunami risk
The 2007 Solomon Island earthquake may point to previously unknown increased earthquake and tsunami risks because of the unusual tectonic plate geography and the sudden change in direction of the earthquake, according to geoscientists. view more (2009-04-10)
Global monsoon drives long-term carbon cycles in the ocean
Monsoon is a global system, and many arrays of evidence indicate that it drives long-term cyclicity of the carbon reservoir in the global ocean. view more (2009-05-08)
Study of 2004 tsunami forces rethinking of giant earthquake theory
The Sumatra-Andaman earthquake of Dec. 26, 2004, was one of the worst natural disasters in history, largely because of the devastating tsunami that followed. view more (2006-03-06)
Sumatra megaquake defied theory
The risks of Sumatra-style mega-quakes around the world have been sorely misjudged, say earth scientists who are re-examining some of the pre-December 2004 assumptions scientists made about such rare events. view more (2006-03-28)
Earthquake in Illinois could portend an emerging threat
To the surprise of many, the earthquake on April 18, 2008, about 120 miles east of St. Louis, originated in the Wabash Valley Fault and not the better-known and more-dreaded New Madrid Fault in Missouri's bootheel. view more (2008-04-25)
Turtles hitchhike across the disciplines
Many species of turtle travel huge distances during their lives, especially open-water feeders such as leatherbacks. A new approach, to be presented at the Society for Experimental biology on Tuesday 1st April, combines field observations with oceanographic theories to attempt to answer some of the puzzles in open-sea turtle biology. Oceanic data... view more... (2003-03-31)
Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. view more (2008-06-26)
Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought. view more (2008-04-11)
