The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe it contains sulfur and nickel, plus smaller amounts of other elements.

The movement of these tectonic plates leads to earthquakes and volcanoes forming. Inner core The inner core is 2900 km below the Earth’s surface, in the centre of the Earth, and is the hottest ...

Scientists have known for a while that Mars currently lacks a magnetic field, and many blame that for its paltry atmosphere – ...

Then there is the outer core, made of liquid metal, and the inner core, a solid ball of metal. At least, that is what scientists thought. New research published in the journal Nature Geoscience ...

If core muscles are tired or weak, the ligaments in your back take over and can become strained. Exercises like side planks and dead bugs work the deep muscles of the inner core, like the pelvic ...

Pilates ring exercises target the core, arms and inner thighs and improve posture. Raven Ross shares exercises for a ...

The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner core is made of solid iron and nickel. The surface of the earth is constantly changing. It's the ...

Energy is needed to keep the dynamo running. This energy comes from the release of heat from the surface of the solid inner core. Although it may seem counterintuitive, material from the liquid ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...
