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

The inner core is responsible for Earth's magnetic field, which acts like a shield, protecting us from harmful solar radiation. This magnetic field might have been important for creating the ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius—made of an iron alloy. The planet’s outer core, beneath the rocky mantle, is a colder, liquid metal. Geophysics models explain that, ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

The magnetic field and the liquid outer core are further stabilized by the more solid inner section. The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth.

Earth’s magnetic field is formed by the movement of the liquid metal, which is generated by the heat that escapes from the core. NOAA NCEI and CIRES Over the past five years, the magnetic pole ...

The satellites monitor the unique magnetic signals that originate from the Earth's core, as well as from the mantle, crust, and oceans and the Earth’s outer magnetosphere.

You can thank the inner core. To understand how Earth’s magnetic field has evolved over its history, geophysicists use models that simulate the thermal state of the core and mantle.

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.

The strength of Earth’s magnetic field and the amount of oxygen in its atmosphere seem to be correlated—and scientists want to know why ...
