Q: Passage: Estimates for the temperature of the outer core are about 3,000 -- 4,500 K (2,730 -- 4,230 ° C; 4,940 -- 7,640 ° F) in its outer regions and 4,000 -- 8,000 K (3,730 -- 7,730 ° C; 6,740 -- 13,940 ° F) near the inner core. Evidence for a fluid outer core includes from seismology which shows that seismic shear-waves are not transmitted through the outer core Because of its high temperature, modeling work has shown that the outer core is a low viscosity fluid that convects turbulently. Eddy currents in the nickel iron fluid of the outer core are believed to influence the Earth's magnetic field. The average magnetic field strength in the Earth's outer core was measured to be 2.5 millitesla, 50 times stronger than the magnetic field at the surface. The outer core is not under enough pressure to be solid, so it is liquid even though it has a composition similar to the inner core. Sulfur and oxygen could be present in the outer core.

Question: Based on this passage, what is the temperature of the earth outer core in fahrenheit? Let's give stream of consciousness first:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The relevant information is: Estimates for the temperature of the outer core are about 3,000 -- 4,500 K (2,730 -- 4,230 ° C; 4,940 -- 7,640 ° F) in its outer regions and 4,000 -- 8,000 K (3,730 -- 7,730 ° C; 6,740 -- 13,940 ° F) near the inner core. Therefore, the final answer is 3,000 -- 4,500 K ( 2,730 -- 4,230 ° C ; 4,940 -- 7,640 ° F ) in its outer regions and 4,000 -- 8,000 K ( 3,730 -- 7,730 ° C ; 6,740 -- 13,940 ° F ) near the inner core.
