Latest Mantle Stories
The inner core of the Earth is simultaneously melting and freezing due to circulation of heat in the overlying rocky mantle, according to new research from the University of Leeds, UC San Diego and the Indian Institute of Technology.
A team of scientists led by Rice University has figured out why the Colorado Plateau â€“ a 130,000-square-mile region that straddles Colorado, Utah, Arizona and New Mexico -- is rising even while parts of its lower crust appear to be falling.
Researchers are hoping to attempt to drill into the Earth's mantle layer off the coast of Costa Rica in hopes of finding pristine samples of the earth's inner boundary.
The continental crust is the principal record of conditions on the Earth for the last 4.4 billion years.
The Moon, Earth's closest neighbor, has long been studied to help us better understand our own planet.
A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior.
While there continues to be considerable debate among geologists about the availability of oxygen in the Earth's mantle, recent discoveries by a University of Rhode Island scientist are bringing resolution to the question.
Researchers at the University of Bristol reveal today in the journal Nature that they have developed a seismological â€˜speed gunâ€™ for the inside of the Earth.
Scientists have wondered for some time why certain seismic waves travel more quickly through the core-mantle boundary, a thin layer of the Earth's interior that lies between about 1675 and 1800 miles below the surface.
The Earth's mantle and its core mix at a distance of 2900 km under our feet in a mysterious zone.
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)....
