Friction Inside The Earth Is A Source Of Heat
There is high temperature inside our planet and the reason is not known yet. A common belief that the Earth`s interior is heated by radioactive elements is now doubted of. Professor Felix Letnikov from Irkutsk Institute of the Earth`s Crust have proposed an idea that the heat is formed in the outer core because of friction between its layers.... view more...

Study uses satellite imagery to identify active magma systems in East Africa's Rift Valley
A team from the University of Miami, University of El Paso and University of Rochester have employed Interferometric Synthetic Aperture Radar (InSAR) images compiled over a decade to study volcanic activity in the African Rift. The study, published in the November issue of Geology, studies the section of the rift in Kenya. view more (2009-11-05)
Fledgling mantle plume may be cause of African volcano's unique lava
Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. view more (2009-03-13)
Seed dispersal in mauritius -- dead as a dodo?
Walking through the last rainforests on the volcanic island of Mauritius, located some 800 km east of Madagascar, one is surrounded by ghosts. view more (2008-05-07)
Why a Rocky Mountain high?
A University of Utah study shows how various regions of North America are kept afloat by heat within Earth's rocky crust, and how much of the continent would sink beneath sea level if not for heat that makes rock buoyant. view more (2007-06-25)
New study shows earthquake shaking triggers aftershocks
A new analysis of earthquake data indicates that aftershocks are triggered by the shaking associated with the mainshock, rather than by the added stress on nearby faults resulting from rearrangement of the Earth's crust. view more (2006-06-08)
Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S. view more (2007-05-11)
Marine Algae A Weapon Against Global Warming?
"Parforce" an EU-funded research project has discovered a new link between marine algae and climate change. Researchers working on the project found out that iodine vapours, released from algae or plankton, condense over oceans to form aerosols . These aerosols, which tend to counter "global warming", can have a significant impact on... view more... (2002-07-18)
SMART-1 diagnoses wrinkles and excess weight on the Moon
Owing to SMART-1's high resolution and favourable illumination conditions during the satellite's scientific operations, data from Europe's lunar orbiter is helping put together a story linking geological and volcanic activity on the Moon. view more (2007-08-23)
New earth observation centres announced
Two new centres which will use satellites and models to help forecast earthquakes and the effects of carbon in climate change were announced (Wednesday 17 October) by Lord Sainsbury, Science & Innovation Minister. Said Lord Sainsbury, " I am delighted to announce that the Natural Environment Research Council is establishing two new... view more... (2001-10-19)
What goes down, must come up: Earth's leaky mantle
A new analysis of the processes that constantly stir the Earth's deep mantle is helping to explain how the mantle holds onto a portion of ancient noble gases that were trapped during the Earth's formation. view more (2009-05-28)
Fossil wood gives vital clues to ancient climates
New research into a missing link in climatology shows that the Earth was not overcome by a greenhouse period when dinosaurs dominated, but experienced rapid fluctuations in temperature and sea level change that resulted in a balance of the global carbon cycle. view more (2006-02-24)
Toxic to aliens -- but key to health of planet
Scientists at the University of Leicester are using an ingredient found in common shampoos to investigate how the oxygen content of the oceans has changed over geologically recent time. view more (2008-06-19)
New deep-sea hydrothermal vents, life form discovered
A new "black smoker"—an undersea mineral chimney emitting hot springs of iron-darkened water—has been discovered at 8,500-foot depths by an expedition funded by the National Science Foundation (NSF) to explore the Pacific Ocean floor off Costa Rica. view more (2007-04-20)
Study outlines eruption at undersea volcano
An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean's surface near the Mariana Islands northwest of Guam. view more (2006-05-25)
Helium isotopes point to the best sources of geothermal energy
With fossil fuel sources depleting and global warming on the rise, exploring alternative means of power for humans is a necessary reality. view more (2007-12-03)
Volcanic plumbing dictates development of deep-sea hydrothermal vents
After years of results that repeatedly dogged him, University of Oregon geologist Douglas R. Toomey decided to follow the trail of data surfacing from the Pacific Ocean. In doing so, he and his collaborators may have altered long-held assumptions involving plate tectonics on the ocean floor. view more (2007-03-22)
Deep sea methane scavengers captured
Scientists of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and the California Institute of Technology (Caltech) in Pasadena succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. view more (2008-05-14)
Measurements link magma melting rate to tectonic plate subduction rate
Determining the origin and rate of magma production in subduction zone volcanoes is essential to understanding the formation of continental crust and the recycling of subducted materials back into Earth's mantle. view more (2007-11-09)
Yale study: Not enough metals in earth to meet global demand
Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever, according to a study published in the Proceedings of the National Academy of Sciences. view more (2006-01-26)
