The core

  • Exhibition Text

    • At the center of the Earth is the dense, hot core. It extends more than halfway to the Earth’s surface, and represents one-third of the planet’s mass. Analysis of seismic waves has shown that the inner core is solid and the outer core molten. The core is composed mainly of iron and nickel. It also contains a light element, probably carbon, oxygen, or sulfur, but which one is unknown.
