The Mississippi River
Transcript of The Mississippi River
Welcome to our presentation on the Mississippi River. Today we will talk about its:
Latitude/Longitude, length, interesting facts, climate zone, location, and its ecological changes that affect the river.
by Belal, Saif & Y-Van 7A
River & Delta:
Functions and Usages
Located in U.S.A at coordinates 29.1536° N, 89.2508° W.
spans through Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana
Source = Lake Itasca
Mouth = Gulf of Mexico
How The Mississippi River *Helped Shape the American/Canadian Border
freshwater inflow (large drainage basin- central/eastern US)
important wildlife habitat (endangered species, migratory birds, recreational fishing, commercial food source)
wetlands provide storm surge protection
tourism (economy support)
navigation & shipping (waterway transportation)
oil & gas production (grouped around the area)
Interesting Facts About The Mississippi River
The Mississippi River is home to 360 species of fish, 326 species of birds, 145 species of amphibians and 50 species of mammals.
The Mississippi River has the third largest watershed in the world.
world's 4th longest river (10th largest)
3,766 km long
20-30 feet wide
450 metres above sea level
average discharge of 593,000 cubic feet per sec
speed of 1.9 km per hour
contains almost 260 species of fish (25% of all the fish species in North America)
humankind = main cause of environmental issues
had been used since way back
used more when European settlers arrived (supply = down, demand = up)
climate change (caused by humans, as well)
climate change affects human (storm by shores = warmth; humans move closer)
population growth = demand growth = supply depleted
less trees (clearing of land) = less habitat
subtropic southern Louisiana can be 13ºC & in subarctic Minnesota it can be -12
In summer it can be 28ºC in Louisiana and 21ºC in Minnesota
average precipitation in south Louisiana = 130 mm; north / great plains = 75 mm; Minnesota 107mm.
In conclusion, the Mississipi River is an important life water source, especially to America. If they have that water, there is availible drinking freshwater, a transportation way, and a wetlands / water habitat for many of the plants and animals.
habitat loss (habitat destruction)
change in migration patterns
commercialization of fish
transportation waterway = foreign vessels; etc = possible invasive species (zebra mussel, reed canary grass, etc)
largest drainage basin in North America- reaches Canada
dendritic river- has tributaries
tributaries: Ohio River, Missouri River (almost as long as the Mississipipi itself), White River, Red River
Gulf of Mexico
