Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

In high school science class, textbooks often feature a recognizable image of the Earth and all its layers—currently, that’s the crust, outer and inner mantle, and outer and inner core.

Earth's inner core is a roughly moon-size chunk of solid iron and nickel that lies more than 3,000 miles (4,800 kilometers) below our feet. It is surrounded by the outer core — a superhot layer ...

Geology Scientists discover strong, ... The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth.

Today, Earth’s core is actually two pieces. There’s an outer layer of molten metal about 1,795 miles thick. Inside that layer of molten metal lies a solid sphere of iron and nickel: the inner ...

The inner core of the Earth appears to hold an innermost secret. ... Kenneth Chang has been at The Times since 2000, writing about physics, geology, chemistry, and the planets.

Imagine Earth’s inner core — the dense center of our planet — as a heavy, metal ballerina. This iron-rich dancer is capable of pirouetting at ever-changing speeds.

“The molten outer core is widely known to be turbulent, but its turbulence had not been observed to disrupt its neighbor the inner core on a human timescale,” Vidale said in a press statement.

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 ...

Earth’s iron-rich inner core may owe some of its surprising softness to the motion of atoms, suggest experiments with iron at high temperature and pressure coupled to AI simulations.
