Copper chains: Study reveals Earth's deep-seated hold on copper
Earth is clingy when it comes to copper. A new Rice University study this week in the journal Science finds that nature conspires at scales both large and small -- from the realms of tectonic plates down t ...
Fragments of continents hidden under lava in the Indian Ocean
The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment known as Mauritia detached about 60 million years ...
Physicists Use Underground Lab to Detect Rare Particles, Peek into Earth's Center
(PhysOrg.com) -- Using a delicate instrument located under a mountain in central Italy, two University of Massachusetts Amherst physicists are measuring some of the faintest and rarest particles ever detected, geo-neutrinos, ...
Haiti: Physics of Quakes Past, and Future
(PhysOrg.com) -- The earthquake that struck Haiti took place along what is called a strike-slip fault -- a place where tectonic plates on each side of a fault line are moving horizontally in opposite directions, ...
Rising mountains, cooling oceans prompted spread of invasive species 450 million years ago
New Ohio University research suggests that the rise of an early phase of the Appalachian Mountains and cooling oceans allowed invasive species to upset the North American ecosystem 450 million years ago.
Too hot, too cold, just right: Testing the limits of where humans can live
On an isolated segment of islands in the Pacific Ring of Fire, residents endure volcanoes, tsunamis, dense fog, steep cliffs and long and chilly winters. Sounds homey, huh?
Earth's breathable atmosphere tied to plate tectonics?
The rise of oxygen is one of the biggest puzzle in Earth's history. Our planet's atmosphere started out oxygen-free. Then, around 3.5 billion years ago, tiny microbes called cyanobacteria (or blue-green algae) ...
A speed gun for the Earth's insides
(PhysOrg.com) -- Researchers at the University of Bristol reveal today in the journal Nature that they have developed a seismological 'speed gun' for the inside of the Earth. Using this technique they will b ...
Melting in the Afar helps scientists understand how oceans form
Lavas from the Afar Depression in Ethiopia, where three tectonic plates are spreading apart, have given scientists a new insight into how ocean basins form.
Scientists reveal Southern California's tectonic plates in detail
Rifting is one of the fundamental geological forces that have shaped our planet. Were it not for the stretching of continents and the oceans that filled those newly created basins, Earth would be a far different ...
Flipped from head to toe: 100 years of continental drift theory
Exactly 100 years ago, on 6 January 1912, Alfred Wegener presented his theory of continental drift to the public for the first time. At a meeting of the Geological Association in Frankfurt's Senckenberg Museum, he revealed ...
Jade sheds light on Guatemala's geologic history
The shifting of tectonic plates in Central America has been poorly understood -- until now. New research on jade found along fault lines in Guatemala is helping geologists piece the puzzle of the past 130 million years.
Keep a lid on it: The controversy over Earth's oldest rocks
New evidence is shedding light on the processes that formed Earth's oldest rock and mineral record – processes that influenced the early evolution of life.
Australian continent to blame for Samoa, Sumatra quakes
(PhysOrg.com) -- The recent earthquakes in the Pacific and Indonesia have one University of Queensland researcher questioning whether the two are related.
