Latest Crust Stories
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.
A new study has uncovered what may be the first recognized example of ancient Martian crust. The rock, designated NWA 7533, holds a wealth of information about the origin and age of Mars' crust.
Scientists have long believed that the moon’s trademark craters were created from the impact of massive asteroids, but new research suggests that smaller planetoids might actually have been responsible for pummeling the lunar surface.
By analyzing basalt, a substance formed from cooling lava, a team of European scientists have gained new insight into how the Earth’s core, crust and atmosphere formed, as well as how volcanic activity originated.
Although long thought to be devoid of life, the bottom of the deep ocean is now known to harbor entire ecosystems teeming with microbes.
Earth’s closest neighbor, the moon, has been studied intently by astronomers for centuries. In that time, we thought we had discovered nearly everything there is to know about the origins of our natural satellite.
Scientists writing in the journal Nature Geoscience say they've unveiled more clues about how continents formed early in the Earth's history.
Real time observation of shear waves on the Earth's surface, first direct observation of subducting continental crust during the collision of two continents
One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet.
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)....
