Midwestern United States Geography
The land in the Midwest is generally thought of as being flat. This is true of several areas in the Midwest, but there are parts that are not flat. For example, the eastern Midwest near the Appalachian Mountains, the Great Lakes basin, and northern parts of Wisconsin, U.P. of Michigan and Minnesota are not flat. Also, the northern part of the Ozark mountain range is in southern Missouri. Prairies cover most of the states west of the Mississippi River. Less rain falls in the western Midwest than in the eastern part. This causes different types of prairies. Areas in northern Minnesota, Michigan and Wisconsin, and the Ohio River valley are not very developed.
