On your answer sheet:
A. How has the geography of the Great Plains helped the region become the "Breadbasket of America"?
Canada and Alaska
The Canadian Shield covers almost half of Canada. The term shield refers to the large core of very old rock that lies at the base of each continent. In North America, this rock core was exposed thousands of years ago. The rest of this sub-region contains islands, lakes, plains, and mountains.
During the ice ages, glaciers scraped across the land, taking the soil with them. They left just a thin layer of soil in eastern and central Canada. The glaciers that scraped the shield also dug the huge holes that became the Great Lakes. These lakes lie between Canada and the United States.They are the world's largest group of freshwater lakes.
To the far north are many smaller lakes and Hudson Bay. The region extends past the Arctic Circle and ends with a scattering of islands.
Continental United States
Two major mountain ranges run through the continental United States. In the east, the Appalachians are a gentle range of rounded peaks and deep valleys. In the west, the Rocky Mountains jut up into jagged, snow-capped peaks. The Rockies reach all the way from Alaska to New Mexico.
Between these two ranges, the great plains stretch across the middle of the continent. This vast, mostly flat region extends about 2,500 miles north and south. From the Rockies, the dry and treeless Great Plains slope down to the central lowlands. The region is mostly flat and covered in grassland. This makes the land very good farmland. Farmers in the Great Plains grow much of the world's corn and wheat. In fact, the region has become known as the "Breadbasket of America."
