What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

A study by researchers at the Australian National University (ANU) suggests the existence of a distinct fifth layer within Earth's inner core, termed an "innermost inner core," located approximately 3 ...

More insights about Earth's core have arrived through some detailed examinations. A team of researchers believes that the inner core is made of two distinct layers. The finding has been explained in ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more about ...

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.

While we can't see deep into the Earth, geologists have a variety of neat tricks to create a picture of our Earth's layers. Just like a kid's jawbreaker, Earth consists of layers that differ in ...
