Beneath Earth s surface, nearly 3,000 kilometers down, lies a mysterious layer where seismic waves speed up inexplicably. For ...

The outer core begins approximately 2,889 kilometers ... layers under immense pressure also creates some increase in temperature. Earth’s internal heat is surprisingly important to live on ...

It's crucial that the core is hot, because these temperatures help create the environment that maintains Earth's vital magnetic field. "Vital" might be an understatement. "The magnetic field is ...

"The inner core is spinning differently then (sic) outer Earth and it actually stopped ... dated data from one area in Greenland, not global temperature change It's expected that scientists ...

Below the Earth's cold, brittle crust and its mantle of molten rock sits the core. Inside the core, temperatures are so hot that metal oozes like a liquid that churns furiously. That's crucially ...

“When the first results came in, we realized that we had literally struck gold,” Nils Messling, a geochemist at Göttingen ...

Earth gets warmer toward its core. At the bottom of the continental crust, temperatures reach about 1,800 degrees Fahrenheit (1,000 degrees Celsius), increasing about 3 degrees F per mile (1 ...

this ignores any interactions with the very hot molten core. Also, notice that this is quite a bit colder than the actual average temperature of the Earth (13.9 C)—a 27.1-degree C difference.

Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and pressures. Determining how iron behaves in these extreme conditions ...

Earth’s inner core is surprisingly soft, and wiggling iron atoms may help explain why. The innermost part of our planet is a solid iron ball smaller than the moon and almost as hot as the ...

The Earth’s inner core is incredibly tricky to study ... For a long time it was assumed to be liquid, due to the extremely high temperatures it faces there. But in the 1930s scientists began ...
