FC: The Regions of North America By: J Kline, T Scarr, and J Guy

1: Topography: In many areas, the streams and rivers of the Intermountain regions and plateaus never reach the sea. Instead they flow into the Brackish Lakes, like the Great Salt lake In Utah, or disappear into desert sinks. But in some regions , some of the rivers do find the ocean. | Climate: The climate of the Intermountain Region is affected by its location and by its elevation. Winters can be cool and wet or hot and dry, depending on the region. In the southern parts of the region the winters are short and warm with little precipitation. The northern portions of the region also lack precipitation, although the climate is more moderate, with moist winters and hot dry summers. | Vegetation: The vegetation of the Intermountain Region ranges between grassland to plants that can barely survive in semi-desert or desert ways! Although the higher areas are covered in thin pine forest.

2: The Western Cordillera Region runs along the west coast of North America. The topography of the Western Cordillera consits of new mountains not yet worn down by erosion. They are more then double as high as the Appalachian mountains in the east. There are many different mountain regions in this region. The Rocky Mountains to the east of the region, which form the continental divide. All of the rivers east of the rockies flow east, finding their outlets in the Gulf of Mexico or the Arctic Ocean, or Hudson Bay and James Bay. West of the Rockies, rivers drain towards the Pacific Ocean. The west coast has a maritime climate. Although it varies from north to south, the west coast is moist and mild. The winters are usually above freezing. Summers are cooler than in the interior of the continent. Western Cordillera vegetation varies enormously from one side of an mountain to the other. On the moist,windward slopes, evergreens, such as Douglas Fir, western hemlock, and western red cedar, grow to tremendous age and size on the lower slopes.

3: The Coastal Plains are lowland area that goes for 3200 km's for Cape Cod, down the continent then turning west and going along the Gulf of Mexico and into Mexico. Topography of the Coastal plains is that there sea level average is low compaired to others. More then half if less then 30 metres above sea level. This area has many swamps and marshes. An important feature is that you can go into the land on rivers such as the Mississippi Delta. This is good for acgriculture and tranportation route. The Gulf of Mexico is where it ends out. | Climate varies quite a bit in Coastal Plains. In the north of the region the winters are snowy and cold with hot humid summers. The southern portions have a sub-tropical climate , with mild to warm winters. The very south is eligiable for Hurricanes in hurricane season. The soils of the Coastal Plains are mainly sandy. The vegetation consists of Sandy soils with some thick jungles. The original vegetation was pine forests.

4: The Arctic Region: The Artic region is very cold and has lots of mountains. Most of the mountains are in the north and the bottom is flat. Everywere is covered in ice. Winter is 10 months long! There's not very much rain so its dry. It is very cold so only shrubs can live, and maybe some moss.

5: The Interior Plains: The Interior Plains are mostly flat with "gentil" hills and deep river valleys. It covers lots of land. It is very high in evelvation as the west can be from 600-1500 metres. The interior plains arent totaly flat as they gently slope down or up. The climate however, is extreme, with freezing winters and long hot summers. It gets colder as you go north. The vegitation has huge grass as tall as a person! Like I said its grassy but there's nice forests in the north.

6: The Canadian Shield is over two million years old. In the Shield, it consists of volcanic mountains that were leveled by millions of years of erosion. Also, there is platforms of rocks that stretch from Labrador, around Hudsons Bay and James Bay, in east, south to the Great Lakes, and west to the Interior Plains.The topography of the Shield is really intense. During the Ice Age, glaciers removed most of the soil, leaving a barren rock surface in many places. The average elevation of the Shield is about 100 meters aobe sea level in the north, rising to about 500 meters in the south.

7: The Great Lakes-St. Lawrence Lowland is the smallest geographical region in Canada. It is formed by the triangle of Lake Huron, Lake Ontario, and Lake Erie. The region is cut by a short extension of the Shield near Kingston, and then continues along the St. Lawrence River. It also includes the Ile d'Anticost, a small island in the Gulf of the St. Lawrence. Topography: The Great Lakes section of the region has a rolling landscape, created mainly by glacation. Flat plains are broken by hills and deep river valleys. The St. Lawrence section consists of flat plains on either side of the river, which gradually begin to rise into the Canadian Shield. Climate: The climate is essentially a humid, continental climate. It is humid because of the presence of the Great Lakes. The Great Lakes tend to cool the temperature during the summer. Vegetation: This region originally was heavily treed. The Great Lakes portion oce had Canada's largest broad-leafed forests. Elsewhere in this region, the vegetation was mixed forests of both decidous and conifers, such as maple, beech, oak, and ash.

8: The Appalachian Region is a mountainous area on the east coast of North America, It extends for 2400 kilometers, form Newfoundland in the north, west through the Maritime provinces, and south through the US as far as Alabama and Georgia. Topography: The Appalachian Mountains are made up of many different mountain ranges. They are old mountains, formed about 300 000 000 years ago. This makes them relatively low as mountain ranges go. Climate: Two currents affect this region; the Labrador Current and the Gulf Stream. The Labrador Current brings cold water that comes from the Arctic. The Gulf Stream brings warm water north from the Carribean. | Vegetation: Originally, the Appalachian Region was heavily forested with mixed coniferous and decidous trees. These could survive in the the poor and unproductive mountain soil, and flourish on the plateaus and in the river valleys, where the soil was much more productive.
