Geoscientists have long thought that water—along with shallow magma stored in Earth's crust—drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, scientists have learned that gaseous carbon ...

A team of researchers from Université Clermont Auvergne, working with a colleague from Universität Bayreuth, has found evidence that suggests the Earth's composition changed over time during its early years via collisional ...
Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth's shell are continuously sinking into the more fluid layer of the planet's mantle over the course of millions of years. Known as lithospheric ...

The Earth's history is written in its elements, but as the tectonic plates slip and slide over and under each other over time, they muddy that evidence—and with it the secrets of why Earth can sustain life.

Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a Mars-sized core. But is this structure universal? Will rocky exoplanets orbiting other stars have the same three layers? ...

(Phys.org)—A team of researchers working on the Borexino Collaboration at Gran Sasso National Laboratory in Italy is reporting that they have detected neutrinos emanating from the Earth's mantle. In their paper published ...
In geology, a crust is the outermost solid shell of a rocky planet or moon, which is chemically distinct from the underlying mantle. The crusts of Earth, our Moon, Mercury, Venus, Mars, Io, and other planetary bodies have been generated largely by igneous processes, and these crusts are richer in incompatible elements than their respective mantles.
