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.
Africa's ups and downs
The East African Rift is an area where two tectonic plates are moving apart, making it a region of high geological activity, home to a number of volcanoes.
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. ...
The case for alien life
Only one planet has been proven to support life: Earth. But evidence is mounting that we are not alone. Biogeochemist Ariel Anbar and astrophysicist Steven Desch, professors in ASU's School of Earth and Space ...
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.
Earth from Space: Peruvian landscape
The foothills of the Andes mountains near the southern coast of Peru are captured by the Kompsat-2 satellite.
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 ...
Location of upwelling in Earth's mantle discovered to be stable
A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: beneath Africa and the Central Pacific. More importantly, Clinton Conrad ...
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.
Noble gases hitch a ride on hydrous minerals
The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't ...
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 ...
New maps show how shipping noise spans the globe
The ocean is naturally filled with the sounds of breaking waves, cracking ice, driving rain, and marine animal calls, but more and more, human activity is adding to the noise. Ships' propellers create low-frequency hums that ...
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 ...
