There is evidence of many pole reversals on the bottom of the Atlantic Ocean. When looking at the Iron on the sea floor, it is aligned in different directions—North and South. If you were to color one direction white and the other black, the pattern would look like a zebra.

It is a fairly regular event and nothing to really get worked up about.

The journal Frontiers in Zoology study, points out that **Dogs poop in alignment with Earth’s magnetic field**.

Yes, we can tell a lot about the timing of these reversals, but the exciting thing about this tree is that we can now get some idea about the impact on living structures and how long these reversals take to happen.
