Physical Regions of North Amercia
- 1. PHYSICAL REGIONS OF NORTH AMERICA
- 2. MAP
- 4. TOPOGRAPHY • Made of many different mountain ranges • Mountains as old as 300,000,000 years • Relatively low mountain ranges with rolling mountains and hills because of erosion • Contains fertile plateaus and river valleys
- 5. CLIMATE • Effected by two oceans • The Labrador current brings cold water south from the Arctic and causes freezing during the winter • The Gulf Stream brings warm water north from the Caribbean
- 6. VEGETATION • Was heavily forested • Had Coniferous and Deciduous trees that can survive in the unproductive soil • Soil was much more productive on the plateaus and in huge river valley
- 7. ECONOMIC ACTIVITY • Fishing in isolated settlements • Mining • Lumbering • Farming
- 8. ENVIRONMENTAL CONCERNS • Mountain removal coal mines
- 10. TOPOGRAPHY • Average elevation of 200m above sea level • Surface is mostly flat or gently rolling • More then half is less than 30m above sea level
- 11. CLIMATE • The North has very cold winters and very hot, humid summers • The South has a sub- tropical climate and mild to warm winters • Subject to hurricanes, occurring between late summer and early winter
- 12. VEGETATION • The soils are mainly very sandy • The natural , vegetation adapted to the sandy soil • Lush jungles have developed in some areas like Mexico • The original vegetation of the area was pine forests
- 13. ECONOMIC ACTIVITY • Tourism and recreation • Shipping at ports • Commercial fishing
- 14. ENVIRONMENTAL CONCERNS • Rapidly growing population • Industrial development
- 15. THE GREAT LAKES
- 16. TOPOGRAPHY • Has rolling hills, mainly creat by glaciation • Flat plains are broken by hills and deep river valleys
- 17. CLIMATE • Essentially a humid continental climate • It is humid because of the presence of the Great Lakes • The lakes can store heat and make winters warmer and can store coolness and make summers cooler
- 18. VEGETATION • Has very fertile soil • Once had Canada's largest broad-leafed forests • In the Great Lakes portion, they had maple, beech, hickory, and black walnut trees • Elsewhere in the region, the vegetation was mixed forests of both deciduous and conifers.
- 19. ECONOMIC ACTIVITY • Farming • Tourism from their natural features • Manufacturing • Lumbering
- 20. ENVIRONMENTAL CONCERNS • Water pollution • Invasion alien species • New chemical contaminants
- 22. TOPOGRAPHY • The US section is divided into Central Lowland and the Great Plains • The Great Plains has a elevation of 600 to 1500m above sea level • In Canada, the plains are generally gently rolling, gradually sloping down from west to east
- 23. CLIMATE • Is a continental climate, affected by its location in the heart of the continent • Has extreme climate with long, hot summers and cold winters • Farther North has arctic climate with extremely cold winters and cool summers
- 24. VEGETATION • Originally was covered with mixed deciduous trees and scattered evergreens in the east of Mississippi • In the Canadian prairie, there's grassland and trees only grown in river valleys • In the North, boreal forest grows and gradually becomes tundra
- 25. ECONOMIC ACTIVITY • Agriculture • Mining • Industry
- 26. ENVIRONMENTAL CONCERNS • Farm pollution seeping into the ground and/or running off into the river and lakes system
- 28. TOPOGRAPHY • Average elevation at about 100m above sea level in the North, 500m in the South
- 29. CLIMATE • Varies greatly • Colder winter in the North
- 30. VEGETATION • Boreal forests cover most of the shield • Some deciduous trees such as poplars and white bitches
- 31. ECONOMIC ACTIVITY • Mining metals and minerals • Paper manufacturing
- 32. ENVIRONMENTAL CONCERNS • Igneous rocks have little capacity to neutralize acid rain from power plants • Increased acidity of lakes levels that fish can't tolerate
- 34. TOPOGRAPHY • New mountains, not yet worn down by erosion • Many different mountain ranges • All rivers flow east
- 35. CLIMATE • Maritime climate • Generally moist and mild
- 36. VEGETATION • Very old and immense evergreens • Rain forest
- 37. ECONOMIC ACTIVITY • Farming • Mining • Tourism
- 38. ENVIRONMENTAL CONCERNS • Acid rain • Air pollution • Nuclear disasters • Distracting of rain forest
- 40. TOPOGRAPHY • Stretches from northern Alaska through the interior of BC then to Mexico • Broad spectrum of land • Has high plateaus and isolated mountain ranges and deserts • Many streams and rivers
- 41. CLIMATE • Winters can be cool and wet or hot and dry depending on its region • In the south, winters and short and warm • In the north, winters are moist and summers are hot and dry
- 42. VEGETATION • Ranges between sparse grasslands to plants that can survive in semi desert or desert conditions • Higher areas are covered in pine forests
- 43. ECONOMIC ACTIVITY • Mining • Cattle ranching
- 46. TOPOGRAPHY • Very flat near the ocean • The mountains far north are covered in glaciers
- 47. CLIMATE • Climate is very severe since it's so far from the equator • Winters lasts 10 months • Summer is very short and not very warm • Because of the little precipitation, the arctic is technically a desert
- 48. VEGETATION • Very few life forms beyond lichen • Trees cannot grow on the tundra • Smaller shrubs, mosses, and lichens are the only thing that can grow
- 49. ECONOMIC ACTIVITY • Extraction of petroleum, mineral, oil and natural gas • Fishing
