Landform Regions And Rock Cycle Flashcards
Alfred wegener?
Person who thought of continental drift (Pangea)
Alfred wegener proof?
Puzzle piece
Fossil evidence
Geological evidence
Glacial evidence
Tectonic plates?
The outer layer of the earths crust. It is where earthquakes happen when they collide. Or the formation of volcanoes/ mountains when there is folding or faulting
Geological eras
Precambrian, Paleozoic, Mesozoic, Cenozoic
Precambrian era
Geological events = erosion filled with sea continuously, ice sheets covered covered North America
Biological events = primitive life forms, no fossils
Paleozoic
Geological events = shallow seas covered North America, Appalachian mountains formed
Biological events = fossils present, age of big fish
Mesozoic
Geological events = formation of Rocky’s began, innuition mountains formed
Biological events = first flowering plants, Jurassic - dinosaurs
Cenozoic
Geological events = glaciers, niagra falls formed
Biological events = human beings, modern forms of life formed
Faults
A fault is a crack in the earths surface/ tectonics plates
Western Cordillera mountain regions
Western cordillera mountain regions are : coastal mountains, interior plateaus, and Rocky Mountains/The Rockies
Western cordillera
Formed by folding and faulting with North American and pacific plates. Highlands. Igneous and sedimentary rock. Farming, mining, tourism, fishing, logging. A lot of valley and rugged mountains.
Interior plains
Shallow seas, sediments from Canadian Shield. Lowland. Sedimentary rock. Wheat agriculture, beef products, oil, oats. Gently rolling hills.
Canadian Shield
Eroded for billions of years so the land is flat. Volcanic activity. Igneous and metamorphic rock. Metallic minerals, lakes and forests, oil, tourism, forestry. Flat land with lots of forests and lakes.
Innuition mountains
Volcanic activity, folding, faulting. Igneous, metamorphic and sedimentary rock. Potential mining but expensive due to it being under glaciers. A lot of mountains.
Hudson Bay-arctic lowlands
Sediments from Canadian Shield compressed in ocean. Sedimentary rock. Bitumen, great whale hydro project (james bay). Flat land
