5.5 million years ago, the access between the Mediterranean and the Atlantic Ocean was closed due to tectonic forces, and a large part of the Mediterranean dried out, much like like the Dead Sea is drying out today. As a result, large deposits of gypsum formed as the sea evaporated, creating the land mass we know today as Spain.
