\u25c7 The outer core, surrounding the inner core, lies between 2900 km and 5100 km below the earth’s surface.<\/p>\n\n\n\n
\u25c7 The outer core is composed of iron mixed with nickel (nife) and trace amounts of lighter elements.<\/p>\n\n\n\n
\u25c7 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.<\/p>\n\n\n\n
\u25c7 The density of the outer core ranges from 9.9 g\/cm3 to 12.2 g\/cm3 .<\/p>\n\n\n\n
\u25c7 The temperature of the outer core ranges from 4400 \u00b0C in the outer regions to 6000 \u00b0C near the inner core.<\/p>\n\n\n\n
\u25c7 Dynamo theory suggests that convection in the outer core, combined with the Coriolis effect, gives rise to Earth’s magnetic field.<\/p>\n","protected":false},"excerpt":{"rendered":"
