North American Grassland 
1. In North America, native grasslands occur primarily in the Great Plains in the middle of the continent. The NorthAmerican prairie biome is one of the most extensive grasslands in the world, extending from the edge of the Rocky Mountain l in the west to the deciduous forest in the east, and from northern Mexico in the south to Canada in the northAverage annual rainfall ranges from about 4Ocm (16 inches) in the west to 80cm (31 inches) in the east. Average annualtemperatures rang between 10 degrees and 20 degrees Celsius (50 to 68 degrees Fahrenheit). In the moist regions ofthe North American grasslands, esp. in the northern Great Plains, rainfall is distinctly seasonal, and temperatures canvary widely from very hot in summer to bitter cold in winter.
2. One hundred years ago, the Great Plains grasslands were one vast, unbroken prairie. Much of the prairie is nowfarmland, the most productive agricultural region in the world, dominated by monocultures of cereal grains. Wheat,barley, soybean, corn, and sunflowers occupy the land that was once prairie. In the areas given over to grazing lands forcattle and sheep, virtualy all the major native grasses have been replaced by alien species.
3. An important feature of the northern Great Plains grasslands is the presence of millions of glacial depressions thatare now small ponds known as prairie potholes. They were formed during the most recent Ice Age, when streamsflowed in tunnels beneath glacialy formed sandy ridges. When the lce Age ended around 12,0O0 years ago, theretreating glaciers created about 25 million depressions across a 300,O0O-square-mile landscapbout 83 potholesper square mile. As the ice blocks melted, much of the water was left behind, forming wetlands ranging in size from atenth if an acre to several acres. The wetlands were soon surrounded by fluttering waves of grasses: shortgrass, m ixedgrass, and tallgrass.
1. AlI of the following statements are true of the northern Great Plains EXCEPT
A. Summer temperatures are very hot, while winter ones are very cold.
B. An unbroken prairie now extends from the western mountains to the eastern forest.
C. The original vegetation consisted of shortgrass, mixed grass, and tallgrass.
D. A large number of small wetlands are found throughout the region.
