There's a story about the Great Lakes and that gulf stream thing?
I forget. All the water broke out and upset the salinity and the current stopped? If so, why are the lakes not salty now? (stupid question)I read about the Mediterranean....how it was a basin and then the land broke at Gibralter and the sea flowed in.
'5 million years agoAfrica was directly joined to Eurasia, with the Alps and the Atlas Mountains piled high on either side of the dry Meditteranean trench. But then the natural dam at Gibralter broke. A gigantic waterfall of sea water, one hundred times the size of Victoria Falls rushed in.'And there's that idea about the Amazon.....how it used to flow the other way and came out around Ecuador (when Africa and South America were joined). Then much later, after the continents had seperated, these mountains sprang up stopping the outward flow and creating a big marsh until finally the Amazon came out in the east.
