Gold is created through complex geological processes, involving intense heat and pressure deep within the Earth’s layers. We'll show you how gold deposits are formed and where you can find these ...

Part of the trouble is that Earth’s deep interior is impossible to observe or sample directly. Seismologists have gleaned information about the inner core’s motion by examining how waves from ...

WASHINGTON, D.C. — Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested ...

According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the surface, as part of a decades-long cycle. Now a new study has reached a surprising conclusion ...

Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal. But that ball may not be as simple as it seems: new research suggests the inner core contains its own ...

Alfred Wilson-Spencer receives funding from NERC grants NE/T000228/1 and NE/V010867/1. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of ...

The new research adds to the mysteries of the planet’s deepest interior region. By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide ...
