Educator Guide: Earth’s Inner Core is Relatively Young
About this guide
Recent research suggests that Earth’s inner core began solidifying sometime after 565 million years ago, just in time to save the planet’s protective magnetic field from collapse and to kick-start it into its current, powerful phase. Use this guide to introduce students to the history and current state of Earth’s magnetic field, the structure of Earth’s interior and concepts related to energy transfer, including thermal conduction and convection.
