Question

How might the reversal of earths magnetic poles affect life on earth?

Answer 1

This is what has happened when the magnetic poles flipped in the past. This could weaken Earth's protective magnetic field b up to 90% during a polar flip. Earth's magnetic field is what shields us from harmful space radiation which can damage calls, cause cancer, and fry electronic circuits and electrical grids.

Answer 2

If that happened it would weaken our protective magnetic field, which wouldn't be able to protect us from the harmful radiations sent through space. This could cause alot of issues like; damage cells, cause cancer, and fry electronic circuits and electrical grids.

Step-by-step explanation:

Earths magnetic field is what protects us from harmful radiation!
