I know that, for no apparent reason, the earth's magnetic field reverses every 
bazillion years or so. Does this happen instantaneously? If so, does it cause 
major weather events, floods, earthquakes, or other cataclysms? If it happens
 gradually, does that mean that occasionally both poles are located somewhere 
on the equator?
