Volcanoes erupt when magma rises through cracks in the Earth's crust, but the exact processes that lead to the melting of rocks in the Earth's mantle below are difficult to study.
4.5 billion years ago in the violent, high-speed environment of the early solar system, a protoplanet roughly the size of Mars was involved in a series of fierce collisions with other large planetary bodies.
The volcanic islands of Hawaii represent the youngest end of a 80 million years old and roughly 6,000 kilometres long mountain chain on the ground of the Pacific Ocean. The so-called Hawaiian-Emperor chain consisting of dozens ...
For decades, researchers have studied the interior of the Earth using seismic waves from earthquakes. Now a recent study, led by Arizona State University's School of Earth and Space Exploration Associate Professor Dan Shim, ...
Contrary to posters you may have seen hanging on the walls in science buildings and classrooms, Lijun Liu, professor of geology at Illinois, knows that Earth's interior is not like an onion.
An international team of researchers led by geoscientists with the Virginia Tech College of Science recently discovered that deep portions of Earth's mantle might be as hot as it was more than 2.5 billion years ago.
If you could travel back in time 41,000 years to the last ice age, your compass would point south instead of north. That's because for a period of a few hundred years, the Earth's magnetic field was reversed. These reversals ...
Whole-mantle convection with tectonic plates preserves long-term global patterns of upper mantle geochemistry
New insights into the convection patterns of the Earth's mantle and its chemical makeup have been revealed by a researcher from the University of Leicester.
Earth's history should include 'pre-plate tectonic' and 'plate tectonic' phases beginning less than a billion years ago, according to a team of geoscientists in the journal Geology.
