Polarity Shift!
A Disneyland kind of a day
A Disneyland kind of a day
The last time I went to Disneyland, a very very long time ago, there were two rides on my mandatory list: Space Mountain and Pirates of the Caribbean. The wait to go on each of those rides was over three hours long. So that was pretty much the whole day.

The Evolution of the Geo-Magnetic Polarity Timescale through time.
Time runs down the figure in Millions of Years (Ma). Every black bar represents a time when earth's magnetic field was in normal polarity (like it is now), and the white represents when magnetic field was flipped so magnetic north shifted to the geographical south pole. Each of these black or white bars are referred to as Chrons in Earth Science.
Each column is a scientific publication showing the understanding of the timing and duration of the polarity shifts, moving from older data on the left to modern data on the right.
Thanks to tumblrs size restrictions this is the scaled down 20 million years long version. I have one running down my office wall that is 90 million years of data. I created this figure with the help of Time Scale Creator software.
