“What would be the effects if the Earth’s core cooled down?”

 

The core of the Earth contributes substantially to the operation of the planet. But what would happen if it were to cool down greatly? Well, let’s think about it. Not only does the core’s high internal temperature (with levels matching the surface of the sun) keep the exterior of the Earth can stay warm in the void of space, but it also serves to sustain the terrestrial magnetic field that shields the Earth from harmful radiation. So if the Earth were to cool down, it would become much like the moon, lacking an electromagnetic shield and being subject to the whims of intense temperature swings.
