Latest Mantle Stories
In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to a new study from researchers at Caltech and the University of Miami in Florida.
While all of Earth’s oceans may seem like more than enough water for one planet, a new study published in the journal Science has revealed an ocean’s worth of water may be sitting in the mantle.
Breaking research news from a team of scientists led by Carnegie's Ho-kwang "Dave" Mao reveals that the composition of the Earth's lower mantle may be significantly different than previously thought.
The contours of the Earth's crust are influenced by the high temperatures deep within the Earth's mantle, according to a new study published in Science.
Seeking to better understand the composition of the lowermost part of Earth’s mantle, located nearly 2,900 kilometers (1,800 miles) below the surface, a team of Arizona State University researchers has developed new simulations that depict the dynamics of deep Earth.
New research from geoscientists at UCLA reveals new information about the forces behind earthquakes by using a technique known as seismic tomography.
Scientists believe that up to three and a half times the water of all the Earth’s oceans could be being transported beneath our feet.
The temperature of the Earth’s mantle during the Archean eon some four billion years ago was significantly higher than it is today, causing the crust to become unstable and drip back down into the mantle, according to research published this month in Nature Geoscience.
Scientists writing in the journal Nature Geoscience say that a similar process to that which allows water to yank oils from ground coffee in order to make a cup of joe in the morning, could be how the Earth's core formed.
Scientists broke new ground in the study of deep earthquakes, a poorly understood phenomenon that occurs where the oceanic lithosphere, driven by tectonics, plunges under continental plates – examples are off the coasts of the western United States, Russia and Japan.
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)....
