|
how to calculate population density??? |
population/km^2 |
|
|
name all 3 rural settlement patterns + describe |
dispersed: not concentrated concentrated: compacted linear:in a line |
|
|
define ecumene |
inhabited land |
|
|
continuous vs discontinuous ecumene |
continuous is large area of inhabited land discontinuous is small, separate areas of inhabited land |
|
|
define region |
large area that has certain characteristics throughout |
|
|
differentiate btwn single & multi-factor regions |
single only has 1 factor throughout multi has many things, ie types of trees, climate, relief makes a region into a multi-factor one |
|
|
define topography |
natural/human landscape features |
|
|
define landform region |
large area with shared natural features
|
|
|
define climate region |
large area with shared climates |
|
|
name all 7 landform regions |
canadian shield, appalachian mountains, inuitian mountains, western cordillera, st lawrence lowlands, interior plains, hudson bay lowlands |
|
|
how is Earth's crust built |
volcanoes, folding, faulting |
|
|
define each |
folding is when 2 parts of a plate push against each other, move up faulting is when 2 plates move vertically or horizontally relative to eachother |
|
|
explain plate recycling |
magma pushes 2 plates apart, plates hit other plates, heavier plate goes under bc of faulting, gets recycled, process starts over again |
|
|
how is earth's crust eroded |
rain, wind, ice (glaciation) |
|
|
define climate |
long-term weather which remains the same |
|
|
define weather |
short-term temperature and precipitation changes |
|
|
continental climate |
changes wildly, a temp range >25 annually <1000mm annual precipitation |
|
|
maritime climate |
more stable, temp range <25 >1000mm annual precipitation |
|
|
westerlies |
prevailing winds coming from the west |
|
|
windward slope |
side that faces the wind |
|
|
leeward slope |
side that faces away from wind |
|
|
rainshadow |
area where there is very little rain due to relief precipitation |
|
|
jet stream |
narrow band of air current |
|
|
chinook |
Warm dry wind that blows down the east side of the rocky mountains |
|
|
why is canada's climate so diverse |
large area, different climate/landform regions, latitude differences |
|
|
factors that affect climate |
L: latitude; how north or south W: winds/air masses/jet streams; see above E: elevation; how high or low R: relief; windward, leeward, rainshadows |
|
|
air masses/ocean currents that affect canada |
gulf stream is warm, makes northeastern trades warm, water affects air, westerlies bring warm air relative to canada temp |
|
|
types of precipitation |
relief, cyclonic, convectional relief: air rises due to relief, cools, rains more on one side convectional: warm air rises, condenses, cools, thunderstorm, heavy clouds cyclonic: cool air moves to warm air, warm rises, cools, rain, water evaporates, warm air rises, cycle |
|
|
wet-climate soil |
less A horizon, worse for growing, less nutrients |
|
|
dry-climate soil |
more A horizon, better for growing |
|
|
leaching |
minerals flow to lower soil levels because of constant water flow |
|
|
calcification |
minerals deposited upwards because of constant upward evaporation of water |
|
|
humus |
organic component in soil |
|
|
which tree can survive winter |
coniferous bc small leaves extend photosynthesis, sap acts as anti-freeze |
|
|
deciduous tree |
wide leaves, sleep in winter |
|
|
coniferous tree |
small leaves, evergreen, long roots |
|
|
how is soil formed |
weathering, decaying organinc matter |
|
|
components of soil |
decaying organic matter, moisture, air |
