Latest Structure of the Earth Stories
Earth today is one of the most active planets in the Solar System, and was probably even more so during the early stages of its life.
Using a diamond-anvil cell to recreate the high pressures deep within the earth, researchers at the California Institute of Technology (Caltech) have found unusual properties in an iron-rich magnesium- and iron-oxide mineral that may explain the existence of several ultra-low velocity zones (ULVZs) at the coreâ€“mantle boundary.
New seismic technique detects boundary between old and new lithosphere.
Researchers discover evidence for the oldest Earth mantle reservoir on Baffin Island.
While prospectors and geologists have been successful in finding diamonds through diligent searching, one University of Houston professor and his team's work could help improve the odds by focusing future searches in particular areas.
Earth could be as much as 70 million years younger than scientists originally believed, according to a new study which claims that it could have taken the planet 100 million years to reach its current size instead of the widely believed 30 million years.
The Moonâ€™s geological past could be better understood by a mineral that Japanese astronomers report they have found.
California's San Andreas fault is notorious for repeatedly generating major earthquakes and for being on the brink of producing the next "big one" in a heavily populated area.
Scientists have used quantum mechanics to reveal that the most common mineral on Earth is relatively uncommon deep within the planet.
University of Calgary researchers listen to earthquake "whispers" reveals new clues about Earth's formation.
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)....
