As iron is the primary component of the Earth's core, its properties (e.g., its melting temperature at the pressures found in the proximity of the Earth's inner core boundary) set an upper limit ...

The Earth's ... Estimates of its temperature vary, but it is probably somewhere between 9,000 and 13,000 degrees Fahrenheit (5,000 and 7,000 degrees Celsius). Above the inner core is the outer ...

Earth’s rocky layers are mysteriously low in nitrogen compared with carbon and argon. A scientific team explored our planet’s ...

Its loss from magma suggests that the planet has a deep reservoir of primordial helium, and the new compounds suggest that Earth’s iron-rich core could hold some of that helium. But the team ...

(High pressures within the Earth cause material to freeze at high temperatures.) This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic ...

(Courtesy: University of Tokyo) Helium deep with the Earth could bond with iron to form ... we need to see the partitioning of helium between iron in the core and silicate in the mantle under high ...

The temperature of the Earth depends on many factors including the concentration of greenhouse gases such as water vapour, methane and carbon dioxide. The Earth also radiates lower frequency ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.
