Researchers find evidence of hot spot that burned eastern underside of US tectonic plate
Geoscientists discover hillslopes can reveal geographic activity below
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.
Newly discovered flux in the Earth may solve missing-mantle mystery
It's widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the Sun, gathering in rocky clumps to form asteroids. ...
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.
Study reveals ancient jigsaw puzzle of past supercontinent
A new study published today in the journal Gondwana Research, has revealed the past position of the Australian, Antarctic and Indian tectonic plates, demonstrating how they formed the supercontinent Gondwa ...
New 'embryonic' subduction zone found
(Phys.org) —A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America.
Infrared photosynthesis: A potential power source for alien life in sunless places
Photosynthesis—the harvesting of sunlight to produce energy—is the ultimate driver of virtually all life on the surface of our planet. Most photosynthetic creatures rely on optical light, the kind we ...
The ascent of man: Why our early ancestors took to two feet
A new study by archaeologists at the University of York challenges evolutionary theories behind the development of our earliest ancestors from tree dwelling quadrupeds to upright bipeds capable of walking and scrambling.
Coral reefs 'ruled by earthquakes and volcanoes'
(Phys.org) —Titanic forces in the Earth's crust explain why the abundance and richness of corals varies dramatically across the vast expanse of the Indian and Pacific Oceans, a world-first study from the ...
GPS solution provides 3-minute tsunami alerts
Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in ...
Western Indian Ocean earthquake and tsunami hazard potential greater than previously thought
Earthquakes similar in magnitude to the 2004 Sumatra earthquake could occur in an area beneath the Arabian Sea at the Makran subduction zone, according to recent research published in Geophysical Research Le ...
Geologic study suggests Earth's tectonic activity peaked 1.1 billion years ago
Study sheds light on Earth's early mantle
(Phys.org) —An international team of researchers, led by scientists at Boston University's Department of Earth and Environment, has found evidence that material contained in young oceanic lava flows originated ...
