summer, tropical maritime air masses, mild and humid. In northern Manitoba:
sub-Arctic conditions.
Terrain: 4 geographical regions: Hudson's Bay lowlands: flat
sedimentary rock. Low Pre-Cambrian plateaux: barren, rocky terrain,
unsuitable for farming, but good for hydro-electric plants, fresh-water
fishing, mining and forestry. Lac Agassiz lowlands and low western
plateaux: these constitute the majority of arable land in Manitoba.
Agriculture: pasture and hay.
Natural resources: nickel, copper, zinc, gold, crude oil, cement, stone (for
construction), sand, gravel, peat and quartz, wood, fish (yellow pike,
coreganeous, perch and black pike), hydroelectric power.
Vegetation:
- to the south: prairies and aspen trees;
- central area: mixed forest;
- to the north: boreal forest;
- vicinity of Hudson's Bay: tundra.
- Elm, ash, maple: along river banks.
- Oak: dry places.
- The prairie gives way to broad-leaved forest
in the north.
- Boreal forest, white and black spruce, grey pine, larch: northern
half.
