Assignment 4 Chapter 11 1. Discuss the physical geography of North America. North America’s physical geography is extremely diverse, in the northeast lays Greenland, which is covered in permanent ice or is in the ice cap biome. There is an ancient core of North America that contains rocks up to three billion years old and is located on the Canadian Shield covering the areas of Nunavut south to Minnesota and northeast to Labrador. As described in the ice cap biome, there is limited agriculture due to harsh climates and poor soils. The resources of the Canadian Shield include; hydropower, wood, iron, nickel, and uranium. Southeast of the Canadian Shield are the Appalachian Mountains. This vast mountain range is located in Northern Alabama and Georgia and runs northeast toward the Gaspe’ Peninsula of Quebec. These mountains are distinguished as the temperate mixed forest biome with richer soils and an abundance of coal. East of the Appalachians between Georgia and New York City, the Piedmont (foothills) is located. In this area the fall line is located; containing good soil to farm and people to populate. Many waterfalls mark the head of navigation to most rivers located here and supply hydropower. Cities found in this area are, Columbia, SC; Richmond VA; Washington, DC; and Philadelphia, PA. Along the east coast is the Atlantic Coastal Plain; the Gulf of Coastal Plain co-insides with the Atlantic Coastal Plain creating a large crescent from eastern Texas up to the New Jersey shore. The biome in this area is coniferous forest with a little savanna mixed in. These areas have sandy and largely infertile soils, a flat topography and many large river mouths flowing out into the ocean. In this area are many important wetlands such as the Everglades and the Great Dismal Swamp.

North of the Gulf Coastal Plain is a small area of highlands containing the Ozark Plateau and the Ouachita Mountains. Divided by the Arkansas River Valley, this is the largest area of uplands between the Appalachians to the East and the Rockies to the West. The Interior North America has a large area that is triangular- shaped comprised of plains. Starting in Texas reaching all the way to Ohio and up to Northern Alberta. The areas located here are in the Mississippi River watershed and the many tributaries including the Ohio and Missouri Rivers. This area is more hilly and more rolling in the east, North of the Ohio River, but slowly evens out farther west, even as the average elevation increases from east to west. The eastern sections of the Interior Plains are built up and agriculture is a used a lot. About one-third of the western region is called The Great Plains; here the biome is a semiarid steppe dominated by short grasses mostly flat with higher levels of elevation. On the Great Plains there is some of the world’s finest soils and most productive farmland. In this region is also the Black Hills and the Bad Lands located in western Dakotas and Eastern Montana. The Rocky Mountains come next; they are found stretching from
