Earth's outer core may hold a hidden 'doughnut'
They found an odd ring around the outer core's equator, where earthquake waves move more slowly than in surrounding regions. Earth's outer core is made up of liquid iron and nickel and surrounds ...
Earth’s Core Might Contain Hidden Helium That Doesn’t Come From This World
Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

The shape of Earth's core is changing
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 ...

Scientists Confirm The Moon Has A Solid Iron Core, Just Like Earth
A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that ...

What Drives Earth's Magnetic Field?
In the Earth (see image below right), the liquid metal that makes up the outer core passes through a magnetic field, which causes an electric current to flow within the liquid metal. The electric ...
Moon’s secret core: Stunning find reveals Earth-like structure inside our cosmic neighbor
Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Forces deep underground seem to be deforming Earth's inner core
Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

Structure of the Earth
Tectonic plates float on the semi-solid mantle, which moves very slowly as a result of convection currents driven by heat energy from the hot core. The outer core is liquid iron and nickel and ...

What's at the center of the Earth?
"The transition from the innermost (solid) ball to the outer shell of the inner core (also solid shell) seems rather gradational than sharp," explains study coauthor Dr. Thanh-Son Phạm.

Scientists reveal evolutionary history of continent-sized regions in the deep mantle
This impacts convection in the outer core—a process that drives the magnetic field and protects us at the surface from harmful cosmic rays. If the African and Pacific LLVP are different ...

Plate tectonics
Its temperatures can reach 5500°C. Outer core The outer core is the layer surrounding the inner core. It is made of liquid iron. Mantle The mantle is the layer of the Earth which makes up 84% of ...
What’s in the Moon’s inner core? Scientists have found the answer!
A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...
