Wild Europe - Genesis 肇始之初- 13

As the sun beat down, something like 4,000 cubic kilometers of water evaporated from the Mediterranean¹ surface every year. And with no Atlantic water to replenish² it, the Mediterranean dried out. In just a thousand years, it became a desert basin of salt pans and caustic³ lakes. The rivers that once fed the Mediterranean cut deeper and deeper into the rock, chasing the dropping shoreline and forming a labyrinth⁴ of dramatic gorges⁵.

Just a few million years ago, France's Rhone Valley must have looked more like the Grand Canyon⁶. So intense was the heat in the basin that these waterfalls evaporated before they even reached the old seafloor. For tens of thousands of years, a natural dam between present-day Morocco and the Rock of Gibraltar held the waters of the Atlantic bay. The Mediterranean basin remained an almost lifeless expanse of salt, sand and parched⁷ earth. But as Africa pushed and pulled Europe's southern boundary, the pressures on the crust became unbearable⁸. Rising tides weakened the land bridge and then the Atlantic burst its way over the precipice⁹. So began the most gigantic flood ever. At its peak, enormous waterfalls a thousand times grander than Niagara thundered into the basin. More than 100 cubic kilometers of water gushed¹⁰ past Gibraltar every day.
