Illinois Waterway
connects Lake Michigan to the Mississippi River
St. Lawrence Seaway
links the Great Lakes with the St. Lawrence RIver
a gated part of a canal or river
flat-bottomed boat
How were the Great Lakes formed?
Thousands of years ago glaciers carved deep pits in the land and then they filled with melting ice.
What effect did changing the flow of the Chicago River have on transporting goods from Lake Michigan?
It let goods be shipped from Lake Michigan to the Missippi River.
If you want to ship fruit form farm in Midwest to Northeast how would you do it?
Trucks are best if for fresh fruits if distance not too far (like here), trains if distance very far (like across country)
What are locks and why are they important?
locks were built so that ships could be raised or lowered to a different level. A lock system helps ships pass through rivers and canals that are at different heights.
What helps link the Great Lakes and the Atlantic Ocean?
The St. Lawrence Seaway
regions of dry hills and sharp cliffs formed of crumbling rock in south Dakota
How did the climate of the Badlands change?
Millions of years ago the climate was warmer and more humid. It was a lush green plain with many plants and animals. Over time the climate became cooler and less humid. Mountains rose and blocked some of the rain. Rivers, wind, and rain carved the landscape.
Badlands National Park
In SW South Dakota, has dry hills and cliffs. Wind and water have carved the cliffs.
the wearing away of rock by water and wind
What does erosion do to the land?
Erosion continually changes the landscape and landforms. It also uncovers fossils in the Badlands.
an area where grasses grow well but trees are rare; the prairie gets much less rain than regions where forests are found.
What was the climate of western South Dakota when dinosaurs lived there?
The climate was warmer and more humid than today. Many plants and animals lived there. Broad rivers flowed through lush, green plains
What caused the climate of the Badlands to change?
The climate became cooler and less humid, then Rocky Mountains and Black Hills rose and blocked some of the rain. Rivers, wind and rain carved the landscape.
Mitchell, South Dakota
Home of the Corn Palace, where the walls are made from corncobs, bundles of wheat, stalks of grass,and kernels of grain.
Big Springs, Nebraska
they grow wheat (oat, barley) and sunflowers and are in the Great Plains
Hoopeston, Illinois
they grow corn and soybeans and are in the Central Plains
Great Plains
An area running North/South across the midwest with 10 - 30 inches of rain per year
Central Plains
An area running east/west unde the Great Lakes with an average rainfall of 30 - 40 inches per year
Why is the midwest an important agricultural region?
The soil is rich and deep. Rainfall is plentiful. THe growing season is long and summers are warm.
crop rotation
the planting of different crops in different years
the process of bringing water to farms and spraying it over the fields.
What effect has irrigation had on the Great Plains?
Lets farmers grow crops that need more water (corn, soybeans) than the Great Plains naturally has
Ten products from the Midwest
Corn, Soybeans, Wheat, hogs, milk & dairy, beef, sunflowers, apples, cherries, peaches, plums, grapes, blueberries, strawberries
Cause: Direction of flow of Chicago River changed
Effect: Links Lake Michigan to MIssissippi RIver so better for shipping
Cause: Large or heavy products have to move long distance at low cost
Effect:Ship by barge
Cause: Glaciers form deep pits and then Ice Age ends
Effect: Melted water from glaciers from Great Lakes
Cause: Illinois Waterway built
Effect: Lake Michigan connects to Mississippi River
Cause: Climate of Badlands gets cooler and less humid
Effect: The landforms change. Rivers, wind and rain erode the land.
Cause: Irrigation on Great Plains
Effect: Farmers able to grow crops that need more water - corn and soybeans
Cause: Midwest has rich, deep soil and long growing season
Effect: big agricultural area - great for farming
Cause: Nearly half the corn in USA grown in central Plains
Effect: CP called corn belt
Cause: great plains don't get as much rain as central plains
effect: irrigation used here.
Cause: Temp of earth rises at end of ice age
Effect: Great lakes formed when glaciers melt
Cause: Sand is flung by wind agains cliff faces
Effect: landscape changes from erosion
Cause: Soybean plants add necessary to soil
Effect: Corn can be grown in soil now
