Reversal of Earth's magnetic poles may have triggered Neanderthal extinction -- and it could happen again The reversal of Earth's magnetic poles, along with a temporary breakdown of the world's ...
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

What a looming geomagnetic flip could really do to Earth?
Earth’s magnetic field has flipped about 170 times in the last 100 m years, and the next reversal is not a matter of if but when. Far from a cinematic instant catastrophe, a flip would unfold over ...
Analysis of fossilized Kauri tree rings reveals Earth's protective magnetic field vanished as poles flipped 42,000 years ago for a millennium, with researchers warning of "massive consequences for ...
Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
Add Yahoo as a preferred source to see more of our stories on Google. Earth in space with a two blue fields emanating from it indicating the planet's magnetic field. Earth, our rocky, watery oasis in ...
Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.
Earth’s magnetic field seems steady and true — reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is currently careening ...
A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...
Earth is surrounded by an immense magnetic field, called the magnetosphere. Generated by powerful, dynamic forces at the center of our world, our magnetosphere shields us from erosion of our ...
Every so often, Earth's magnetic poles completely flip. What causes this to happen? And how do these reversals affect life on Earth? When you purchase through links on our site, we may earn an ...
