The Hidden Architecture of Earth's Interior Earth's structure resembles a giant onion with distinct layers, each playing a ...

NORFOLK, Va. — Fault lines are fractures or breaks in the Earth's crust where tectonic plates move past each other, often resulting in earthquakes. These geological features are classified into three ...

Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

The center of Earth lies around 4,000 miles under our feet — but what lies beneath the outer crust and the inner core? When you purchase through links on our site, we may earn an affiliate commission.

Why do some earthquakes release more energy than others? A research team led by Prof. Dr. Armin Dielforder from the University of Greifswald has managed to demonstrate a clear physical connection ...

A new study adds evidence to the idea that Earth's inner core is slowing its spin, though still rotating in the same direction as the planet. KATERYNA KON / SCIENCE PHOTO LIBRARY via Getty Images The ...

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing. The ...

Atoms within the enormous ball of iron in Earth's inner core may move around much more than previously thought, which could explain recent findings about the core's surprising softness. When you ...

Magnetic data suggest Seattle's fault line formed 55 million years ago, when the southern half of a subducting chain of volcanic islands piled onto the continent and tore apart from the northern half.
