The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

A deep learning-based scheme is proposed for automated and efficient processing of teleseismic phases. 1. The validation with ...

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

Something strange is stirring deep beneath Earth's surface. Just a few decades ago, human activity set off a slow-motion ...

Beneath the crust of North America, scientists have found that the deep roots of the continent are slowly dripping away in ...

Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at the heart of the planet. But new research has revealed something much more ...

In the middle of the Pacific Ocean, thousands of miles from any continent, Easter Island rises out of the sea. Its surface ...

The deep roots of Earth's oldest continents have long been thought to be unshakable. But a new seismic discovery suggests that even these stable landmasses can change. Beneath the center of North ...

Establishing a direct link between the Earth's interior dynamics occurring within the first 100 million years of its history and its present-day structure, the work is one of the first in the ...

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...

Many geologists attribute the great variation in the temperature gradient to complex irregularities in the structure of the earth's crust. Some even maintain that the interior of the earth is cold ...
