At the center of the Earth lies a hot, solid inner core composed predominantly of nickel and iron, with a radius of approximately 1,200 to 1,300 kilometers. This inner core is surrounded by a ...

USC scientists have made a groundbreaking discovery about the nature of the Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing. The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found ...

This metallic inner core, about 1,500 miles wide, was discovered in the 1930s. Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging ...
