The outer layer, comprised of liquid iron alloy, is about 1,355 miles thick. The outer core is also thought to be responsible for Earth’s magnetic field.

Earth is composed of four distinct layers, based on their density. The outermost layer is called crust, then comes the mantle, followed by the outer core and finally, the inner core, which is ...

Journey To The Centre Of The Earth Gets Deep After Researchers Discover 5th Inner Core Layer During school we have only studied d about the 4 layers -the crust, mantle, liquid outer core and solid ...

Scientists have found that there is an extra innermost core at the center of the Earth made entirely of iron, measuring 400 miles in diameter.

“Traditionally we’ve been taught the Earth has four main layers: the crust, the mantle, the outer core and the inner core,” Joanne Stephenson, lead author of the work, said in a statement.

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, ...

Finally, there’s the core. The liquid outer layer of the core is responsible for producing Earth’s magnetic field, which is further stabilized by the solid inner section.

Scientists have uncovered new signs of a mysterious structure buried deep inside Earth’s inner core, pointing to the possibility of a fifth distinct layer within the planet. The discovery, detailed in ...

The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth's interior.

Water leaking from the surface of the Earth could be changing the outer rim of our planet's core and wrapping it in a layer of crystals, according to a study.

The Earth consists of four main layers: the crust, the mantle, the outer core and the inner core.
