In fact, Earth's outer core is approximately 5 to 10 percent lower density than iron at Earth's core temperatures and pressures. Hence it has been proposed that light elements with low atomic numbers comprise part of Earth's outer core, as the only feasible way to lower its density. Visa mer Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. The outer core begins approximately 2,889 km (1,795 mi) beneath … Visa mer Composition Earth's outer core cannot be entirely constituted of iron or iron-nickel alloy because their densities are higher than geophysical measurements of the density of Earth's outer core. In fact, Earth's outer core is … Visa mer 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 … Visa mer WebbOuter Core 9.9 - 12.2 1.5 - 3.1 5000 - 6300 Inner Core 12.8 - 13.1 3.1 - 3.6 6300 - 6700 State and draw the following relationships: Depth vs. Density Depth vs. Pressure Depth vs. …
