Mississippi River Formation
The Mississippi, like most rivers, was formed when ice began to melt ending the Ice Ages. As the glaciers receded, they carved large troughs in the earth's surface carrying the melting snow and ice, as water, to the sea. Over the millenium, silt from the upper regions of the Mississippi would deposit themselves as sand barges further downstream. Most but not all of the sand barges would be carried further downstream and deposited at sea level close to the river's mouth. Force from the river waters would continue gouge the soft soil to make the Mississippi Delta.

Geological history[edit]
The Pacific Ocean developed from the Panthalassa following the breakup of Pangaea. There is no firm date for when the changeover occurred, as the replacement of the sea bed is a continuous process, though reconstruction maps often change the name from Panthalassic to Pacific around the time the Atlantic Ocean began to open.[41] The Panthalassic Ocean first opened 750 million years ago at the breakup of Rodinia,[41] but the oldest Pacific Ocean floor is only around 180 Ma old.[42]
