Earth outer core temperature
Unlike Earth's solid, inner core, its outer core is liquid. Evidence for a fluid outer core includes seismology which shows that seismic shear-waves are not transmitted through the outer core. Although having a composition similar to Earth's solid inner core, the outer core remains liquid as there is not enough pressure to keep it in a solid state. Seismic inversions of body waves and normal modes constrain the radius of the outer core to be 3… WebApr 14, 2024 · The layer of the Earth that experiences the highest temperature is the outer core. Temperatures in the outer core can reach up to 5,500°C (9,932°F) due to the intense pressure and heat generated by the Earth's radioactive decay and residual heat from its formation. The outer core is a liquid layer composed of molten iron and nickel that ...
