In the west, wind blowing over sandstone, carrying grains of sand, hitting more grains of sand. The northeast deals with temperature changes with ice freezing and melting, getting into the crystalline structure of granite and wedging it apart. In the midwest, with its abundant water, combining with the carbon dioxide, causes chemical weathering on limestone. Southeastern areas have higher amounts of rainfall, combined with generally softer landforms including clay, allows high rates of water erosion, plus the warmer climate causes higher rates of biological weathering. http://geology.teacherfriendlyguide.org/index.php?option=com_content&view=article&id=87:topography-of-the-northeastern-us-a-brief-review&catid=40:topography&Itemid=107 (ice in the northeast) http://water.usgs.gov/ogw/karst/aquifers/midwest/index (midwest limestone) http://dge.stanford.edu/SCOPE/SCOPE_32/SCOPE_32_2.5_Chapter12_407-428.pdf (water erosion) Can't do your homework for you but here's a start with some possible links to check out hope it helps!
