Ask AI: If the earths inner core stops what are the effects?

If the Earth's inner core were to stop, the effects would be catastrophic. Without the inner core's heat source, the outer core would be too cool to generate the earth's magnetic field. This would lead to a decrease in protection against solar radiation, resulting in increased temperatures on the Earth's surface and a greater threat of damage from solar storms. Additionally, it would result in significant shifts in tectonic and volcanic activity, possibly resulting in earthquakes, tsunamis, and other natural disasters.
