Hint:
This part of the core is also created with iron and nickel, just in liquid form. It sits roughly 5,180 km to 2,880 km below the exterior. Heated mainly by the radioactive deterioration of the components uranium and thorium, this liquid roils in enormous, raging streams.

The temperature is $6740{\text{ - }}13940^\circ {\text{F}}$ adjacent to the inner core. Verification for a watery outer core contains from seismology which demonstrates that seismic shear-waves are not spread through the outer core. Due to its high temperature, exhibiting work has revealed that the outer core is a low-viscosity liquid that convects wildly. The dynamo theory perceives eddy fluxes in the nickel-iron liquid of the outer core as the major source of the Earth's magnetic field. The outer core is not under adequate compression to be solid, so it is liquid even though it has a configuration parallel to the inner core. Sulphur and oxygen could be existing in the outer core.
