The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer—like the ...

Planetary Potato: Earth has a complex internal structure consisting of a solid iron-nickel core at the center and a liquid outer core. The interaction between these two elements can significantly ...
