The Earth's outer core is a sea of molten metal.

The outer core of the Earth is a liquid layer about 2,266 kilometers thick.

Sulfur and oxygen could also be in the outer core.

For example, we can say with much confidence that the outer core of the Earth is a fluid.

The density of the outer and inner cores can only be estimated by indirect means.

The liquid outer core also appears to have density 5 to 10% lower than iron.

Without the outer core, life on Earth would be very different.

Interactions between the inner and outer core create the magnetic field.

Industry, however, is willing to pay to be in the outer core.

This reduces the energy of the shock, which can stall the explosion within the outer core.
