Badlands
|
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.
|
|
erosion
|
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.

|
|
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
|
|
irrigation
|
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
|

|
|
Cause: Irrigation on Great Plains
|
Effect: Farmers able to grow crops that need more water - corn and soybeans
|
|
