Unit 2 Flashcards
Plate tectonics evidence 5-6
Puzzle pieces; rock formations, fossils and animal species, earthquakes and volcanoes, magnetized rocks
Where does the earth get its energy
Earth gets its energy from convection currents caused by the radioactive core
Regions of Canada 8
Great Lakes and st Lawrence lowlands, Canadian Shield, western cordillera, interior plains, Appalachian mountains, Inuittian mountains, arctic lowlands, Hudson Bay lowlands
Climate definition
Average long term weather patterns in a given area
Factors that afffect climate 6
Lattitude-more or less direct sunlight
Ocean currents-transport warm air from equator and cold air from poles
Winds adapt to temperature of water masses
Elevation temperature drops as elevation increases
Relief mountains act as a barrier high altitude air is less likely to retain heat
Near water water heats and cools slower than land moderates temperature
Soil
7 types
Type 1 is best
70% of type 1 soil can be seen fromCN tower
Prairies 3-4
Most of Canada 6-7
Humus
The organic part of soil such as leaves that have been decomposed
Transition zones
Land begins to change
Coniferous and Deciduous trees
Con-needle trees with cones
Deci-she’d leaves seasonallly
Boreal forest
Forest in high latitudes where freezing temperatures occur for 6-8 months
Permafrost
Ground that is permanently frozen
Tundra
Flat treeless landscape where subsoil is permanently frozen
Eco zone
Area with similar characteristics if vegetation, soil, climate, rock forms, energy, land forms, etc. Canada has 15 terrestrial and 5 marine . We live in the mixed wood plains.
Layers of the earth
Inner core, outer core, mantle, crust
Convergent plate boundary
Come together Up mountains, down trench
