Which Earth layer is roughly 6,000 kilometers below the surface?

Which Earth layer is roughly 6,000 kilometers below the surface?

• A. Crust
• B. Mantle
• C. Outer Core
• D. Inner Core

Answer: (D)

At about 6,000 kilometers below the surface you’re near Earth's center. The inner core begins around 5,150 kilometers beneath the surface and continues to the center, about 6,371 kilometers from the surface. So being roughly 6,000 km down places you inside this deepest layer, the solid sphere mainly made of iron and nickel. The crust is only a thin outer skin, the mantle extends down to ~2,900 km, and the outer core runs from ~2,900 to ~5,150 km, all shallower than 6,000 km.
