Latest Asthenosphere Stories
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.
A layer of partially molten rock about 22 to 75 miles underground can't be the only mechanism that allows continents to gradually shift their position over millions of years.
Scientists interested in the construction of the rock layers immediately under the Earth’s crust, the lithosphere and asthenosphere, have new tools to help analyze these layers and further understand plate tectonics.
Rifting is one of the fundamental geological forces that have shaped our planet. Were it not for the stretching of continents and the oceans that filled those newly created basins, Earth would be a far different place.
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.
For many people, Global Positioning System (GPS) satellite technology is little more than a high-tech version of a traditional paper map.
India slides under Tibet, but how?
HOUSTON, Sept. 1 /PRNewswire-USNewswire/ -- Why do we still find rocks from the Archean, one of the earliest geological eons on Earth dating from about 3.8 to 2.5 billion years ago? This is an apt question as our planet is one of the most dynamic in the solar system.
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)....
