The Messinian Salinity Crisis, most commonly referred to as MSC, is considered to be one of the most dramatic events to occur in the geology of the world in about twenty million years. The Messinian Salinity Crisis is essentially when the Mediterranean Sea dried up completely. The sea began to dry up approximately 6 million years ago and ended around 5.3 million years ago. Prior to the drying of the sea, the sea level in the oceans had dropped about 70 meters because of global cooling which led to the glaciers and icebergs. Because of this, the connection between the Atlantic Ocean and Mediterranean Sea had become nonexistent and the Mediterranean could not depend on the Atlantic for the source of water. With the Mediterranean Sea being directly located about the Sahara Desert, which is considered to be the driest place in the world, the Mediterranean Sea is susceptible to evaporating because of the location. The Mediterranean Sea then became a very large basin, almost similar to the Grand Canyon. With this canyon being right next to the Atlantic Ocean, there was a lot of wind and this canyon experience erosion over time. The wall between the Atlantic Ocean and where the sea use to be, became very weak due to this erosion. The wall then must have broken and the canyon became full of water again.
Around forty years ago, an oil drilling company was drilling in the Mediterranean when they stumbled across very large salt deposits. When the Mediterranean Sea began to dry…
