\u25c7 Inner core extends from the centre of the earth to 5100 km below the earth’s surface.<\/p>\n\n\n\n
\u25c7 Inner core is generally believed to be composed primarily of iron (80%) and some nickel (nife).<\/p>\n\n\n\n
\u25c7 Since this layer can transmit shear waves (transverse seismic waves), it is solid. (When P-waves strike the outer core \u2013 inner core boundary, they give rise to S-waves).<\/p>\n\n\n\n
\u25c7 Earth’s inner core rotates slightly faster relative to the rotation of the surface.<\/p>\n\n\n\n
\u25c7 The solid inner core is too hot to hold a permanent magnetic field.<\/p>\n\n\n\n
\u25c7 The density of the inner core ranges from 12.6 g\/cm3 to 13 g\/cm3.<\/p>\n\n\n\n
\u25c7 The core (inner core and the outer core) accounts for just about 16 percent of the earth’s volume but 33% of the earth\u2019s mass.<\/p>\n\n\n\n
\u25c7 Scientists have determined the temperature near the Earth’s centre to be 6000\u05afC.<\/p>\n\n\n\n
\u25c7 At 6000\u00b0C, this iron core is as hot as the Sun\u2019s surface, but the crushing pressure caused by gravity prevents it from becoming liquid.<\/p>\n","protected":false},"excerpt":{"rendered":"
