Plate tectonics: What set the Earth's plates in motion?
The mystery of what kick-started the motion of our earth's massive tectonic plates across its surface has been explained by researchers at the University of Sydney.
Pacific plate shrinking as it cools: Calculations challenge assumptions about rigid lithosphere
The tectonic plate that dominates the Pacific "Ring of Fire" is not as rigid as many scientists assume, according to researchers at Rice University and the University of Nevada.
World's tectonic plate movement mapped
A group of geophysicists is testing the hypothesis that the rate of "supercontinent assembly"—or tectonic plate movement—changes over time.
Scientists detect evidence of 'oceans worth' of water in Earth's mantle
Researchers have found evidence of a potential "ocean's worth" of water deep beneath the United States.
Image: Messy peaks of Zucchius
Even to the naked eye, our Moon looks heavily cratered. The snippet of carved and pitted lunar surface shown in this image lies within a 66 km-wide crater known as Zucchius. From our perspective, Zucchius ...
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) ...
Colliding plates form Kimberley 'Alps'
A geological survey has confirmed that a section of the North Australia Craton was forced under its neighbouring tectonic plate and in the process created the hills that stretch from Halls Creek up to Kununurra ...
US Titanic discoverer embarks on new mission
US ocean explorer Robert Ballard, famed for his 1985 discovery of the Titanic, embarked Wednesday on an expedition in the Caribbean and the Gulf of Mexico.
ESA image: Mount Kenya from orbit
Mount Kenya, the second-highest mountain in Africa, is pictured in this image from Japan's ALOS satellite from 25 February 2011.
New insight into the temperature of deep Earth
Scientists from the Magma and Volcanoes Laboratory (CNRS) and the European Synchrotron, the ESRF, have recreated the extreme conditions 600 to 2900 km below the Earth's surface to investigate the melting ...
Diamond planets may be more common than astronomers thought
(Phys.org) —Carbon-rich planets may be more common than previously thought, according to new research by Yale University astronomers.
How cosmic crashes could have kickstarted plate tectonics
A rock the size of a small city hurtles towards Earth, smashing a crater bigger than the span between Washington, D.C. and New York City. The heat and shockwave raises the temperature of the atmosphere above ...
New discovery helps solve mystery source of African lava
Floods of molten lava may sound like the stuff of apocalyptic theorists, but history is littered with evidence of such past events where vast lava outpourings originating deep in the Earth accompany the breakup ...
