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 ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...

There is more to Earth than what we can see on the surface. Both the exterior and interior regions of the planet are made up of many layers with various properties. These layers are formed because of ...

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 ...

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.

The Earth with the upper mantle exposed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock approximately 100 miles beneath the Earth's ...

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 ...
