Latest Mantle Stories
For a long time now, scientists have been convinced that lava that has erupted from certain oceanic volcanoes contains material from the crust of early Earth, but decisive evidence has been elusive.
Volcanism in the Yellowstone region was caused by the defunct pieces of a former mantle plume that were severely deformed. Circulation currents, driven by the movement of tectonic plates at the Cascades subduction zone, also affected the plume.
According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions.
Scientists from the University of California, San Diego’s Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet’s mantle – a substance which could be acting as a lubricant of the sliding motions of the Earth’s tectonic plates.
Researchers wrote Earth's interior cycles have contributed to long-term sea-level rises and climate change.
A University of Utah seismologist analyzed seismic waves that bombarded Earth's core, and believes he got a look at the earliest roots of Earth's most cataclysmic kind of volcanic eruption. But don't worry. He says it won't happen for perhaps 200 million years.
According to a new study, the Earth's mantle magma melts far hotter and deeper in the Earth's core than previously thought, a discovery that will have lasting implications for geologists.
A global team of drillers, geologists and other scientists and researchers plan to spend $1 billion to go the other way, deep into the Earth’s mantle.
On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle.
Leptopecten latiauratus, the common name being the kelp scallop, is a small saltwater clam, a bivalve mollusk belonging to the family Pectinidae. It resides in water up to 850 feet deep. Similar to other scallops, it has many small primitive eyes around the rim of its mantle and escapes its predators by jet propulsion. The shell can be anywhere between 3 to 5 centimeters in size. It is mostly circular with two flat auricles or ears that extend off of the hinge. It usually has ridges that...
Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
