(unit 3) Canadian Connections/Methods of Geographic inquiry Flashcards
Moraines
hills or ridges with thin soil and swamps from ice sheets/glaciers
have deposited along the edges
Drumlins
egg shaped hills
-one wide steep side and the other more gentle
Eskers
formed when rivers flowing in or under melting glaciers, that are depositing sand/gravel
Canadian Shield
makes up half of Canada and it is mostly made up of igneous and metamorphic rocks
Lake Agassiz
was a huge lake from an ice sheet that submerged canada before it drained
Tundra
vegetation region found in the north-most cold climates and does not have trees but had bushes grasses and mosses instead
Leaching
removal of minerals on the top layer, and moving them downwards
-occurs in wet climates
Calcification
evaporation of water going to the surface placing minerals upwards
-occurs in dry climates
Plate Tectonics
a theory that our Earths outer shell is made up of about 20 plates that constantly are moving
Maritime Climate
temperature range between highest and lowest monthly average temperature is small and precipitation level is higher
Continental Climate
far from oceans and large lakes
-interior of land masses have a continental climate
Faulting
is fractures in bedrock along where movement has taken place and appear in the earths crust by stress of convention currents that occur in the mantle, if rock is brittle or bends quick, it breaks and forms a fault
-known when one block is displaced vertically in comparison to the other
Folding
pressure being pushed into the middle of the earths crust
-pressure buckles or folds into a series of ridges
(rockies and appalachian)
Potash
Made when ancient seas evaporated leaving mineral deposits
Fjords
narrow deep inlets of sea between high cliffs
