The Mississippi River is a river in the United States. It is the 11th longest river in the world. Its largest city is Memphis, Tennessee.

The name "Mississippi" comes from a Native American name that means "big river". The source of the Mississippi is Lake Itasca in Minnesota, near the border with Canada. The Mississippi flows south through the middle of the United States. It flows through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, and Mississippi. The mouth of the Mississippi is in the state of Louisiana, south of the city of New Orleans. The Mississippi flows into the Gulf of Mexico.

At the end of the Mississippi there is a zone in the Gulf of Mexico where very few animals can survive comfortably because of the fertilizer and other chemicals that run off of farms into the river and its tributaries. The rivers then carry them into the gulf.^[4]

1. ↑ The United States Geological Survey recognizes two contrasting definitions of a river's source.USGS.gov By the stricter definition, the Mississippi would share its source with its longest tributary, the Missouri, at Brower's Spring in Montana. The other definition acknowledges "somewhat arbitrary decisions" and places the Mississippi's source at Lake Itasca, which is publicly accepted as the source,USGS.gov and which had been identified as such by Brower himself.MT.gov Archived 2012-01-18 at the Wayback Machine
