Geograohy - Unit 2 Flashcards
Continuous ecumene
The part of the country where there is continuous permanent settlement.
Discontinuous ecumene
The part of the country where there are significant patches of settlement.
Rural settlement
Farm like settlement
Urban settlement
City like settlement
Survey system
A grid system used to locate and identify parcels of land and roads.
Dispersed population
A population spread evenly across the land which is common in agricultural areas.
Concentrated population
A population focused in patches with specific resource industries such as mines or paper mills.
Linear population
A population settled along a line such as a coastline, river or highway.
Continental drift
Theory developed by Alfred Wenger.
300 million years ago, Earth’s masses collided into a super continent called, Pangaea.
Plate tectonics
Theory by J. Tuzo Wilson. The earth’s crust is actually floating on molten rocks inside earth. The crust is not a single piece bu is made up of dozens of plates called plates. The mountains in the east and west of Canada grew as a result of plates colliding. The movement of plates has also played a role in the formation of Canada’s fossil fuels- oil, gas, coal. The plates cause earthquakes, volcanoes and mountains.
Glaciation
The process of ice advancing and covering large areas of land. Glaciation is important to the creation of Canadian landforms.
Alpine vs. Continental Glacier
Alpine glaciers are smaller, found in mountains and move due to gravity.
Continental glaciers are ice sheets that cover massive areas (Geeenland). When they move, they smooth or erode the surfaces below.
Till
A mixture of loose sediments and rocks of all sizes that are deposited by Glaciation.
Erosion
The moving of broken up pieces of rock.
Deposition
Occurs as a result of Glaciation. Deposition occurs as either ice (till plains, moraines) or meltwater (moving water, still water).
