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 ...

Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

A new study provides the best evidence yet for a hidden layer deep within Earth’s solid inner core. Earth’s inner core, made of solid iron and nickel, is roughly two-thirds the size of the moon. The ...

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 ...

SALT LAKE CITY, March 23, 2015 - By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets ...

Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

A team has updated its asteroid bombardment model of the Earth with the latest geologic evidence of ancient, large collisions. These models have been used to understand how impacts may have affected ...

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 ...

This layer makes up only 1% of the entire volume of the Earth, though it makes up the entire surface (the continents and the ocean floor). The thinner parts are the oceanic crust, which underlies the ...
