Earth's magnetic field became weaker during this period, falling to at least 5% of its present strength. This made it possible for more cosmic rays to enter the Earth’s atmosphere, according to ...

The magnetic field lines start to pinch together and connect to form a tail on Earth — literally called a magnetotail. But the tail’s stretched field lines become unstable and snap.
