Earth's Core Deprived Of Oxygen
2011-11-24 04:57:19

The composition of the Earth's core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well.

New Model May Explain Magnetized Moon Rocks
2011-11-10 06:06:46

A team of scientists has proposed a novel model for the generation of a global magnetic field in the ancient moon, which could help solve a decades-old mystery about the presence of magnetized rocks on the moon’s surface.

Princeton Model Shows Fallout Of Giant Meteorite Strike
2011-10-20 04:50:33

Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions.

Southern California's Tectonic Plates Revealed In Detail

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.

Diamonds Show Carbon Cycle May Reach Earth's Lower Mantle
2011-09-16 10:41:51

By studying the chemistry of an unorthodox set of Brazilian diamonds, a team of researchers have discovered startling new information about the carbon cycle and the theory of plate tectonics.

Siberian traps and their relation to the mass extinction 250 million years ago.

Meteorites May Have Brought Precious Metals to Earth
2011-09-08 04:20:54

Precious metals such as gold, platinum and tungsten were brought to Earth by a massive meteorite shower that occurred approximately 650 million years after the planet formed.

New research from Matthew Jackson and Richard Carlson proposes that the remnants of six of the largest volcanic events of the past 250 million years contain traces of the ancient Earth's primitive mantle—which existed before the largely differentiated mantle of today—offering clues to the geochemical history of the planet.

Seismology
2014-01-12 00:00:00

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...

Meteorite -- A meteorite is a relatively small extraterrestrial material body that reaches the Earth's surface. While in space these bodies are called meteoroids. Upon entering the atmosphere air drag and friction will cause the body to heat up, emitting light, thus forming a meteor, fireball, or shooting star. Most meteors disintegrate in the air, making impact events (Earth impacts) on the surface of Earth uncommon. About 500 baseball sized rocks a year reach the surface. Large...

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)....
