The outer core of the earth facts
WebbEarth is made up of four layers namely: crust, mantle, outer core and inner core. As you go below the surface of the earth, the temperature rises. This is because the earth’s core is very hot. The outer core is a semi-liquid while the inner in solid. The core is made up mostly of minerals mostly Iron (Fe) and Nickel (Ni). WebbScientific history. Earth was discovered to have a solid inner core distinct from its molten outer core in 1936, by the Danish seismologist Inge Lehmann, who deduced its presence by studying seismograms from …
The outer core of the earth facts
Did you know?
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 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 par… Webbför 2 dagar sedan · We guarantee you’ll have it in your basket on repeat.
