Latest Structure of the Earth Stories
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.
NEWARK, Del., Jan.
A new analysis from a team of American researchers has found the volcanic plume that created the Galapagos Islands isn’t where models have projected it.
The standard model for mountain structure, in which high topography must have deep roots for support, is defied by the Atlas Mountains, according to a new study from the Earth Sciences department at the University of Southern California.
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.
A University of Houston (UH) geoscientist and his colleagues are revealing new discoveries about the Earth's development, following a major international expedition that recovered the first-ever drill core from the lower crust of the Pacific Ocean.
When you think of the Antarctic, images of snow, ice and glaciers are the usual associations. We forget that it is also a region of fire, dotted with volcanoes on the mainland and the surrounding islands.
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand.
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.
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)....
