15. TUNDRA REGION
This region which
incudes the Hudson
bay is situated to the
north of the artic
circle
(661/2degree north).
Severe cold and a
long winter
TUNDRA REGION

16. THE TAIGA REGION
Extending from New
Foundland in the east to
Alaska in the
west,coniferous forests can
be seen
Warm and short winters
Main occupation here is
lumbering and fur trade
TAIGA REGION

17. THE TEMPERATE EAST MARGIN
REGION
It is located to the east of the great
lakes and the Appalachian
mountains.
Due to the influence of the Cold
Labrador Current in the west
winters are very cold.
Rain is experienced here in
summers.In south the summers
are very hot and winters are
mild.The coastal region
experiences cyclonic winds like
Hurricane and Tornado.

18. COOL TEMPERATE WESTERN
MARGIN
It extends from the north of
California to Alaska.
The warm Alaska current
that flows through these
shores make the summers
hot and winters cool.
The proximity to the rocky
mountains helps in ensuring
heavy rain fall in the region.
Coniferous forests are
mostly found here.

19. THE PRAIRIE GRASLANDS
It extends from the south of Taiga,
the region between the Great lakes
and the rockies, to the missouri­mississippi
basin.
Short grass is the vegetation seen
here.
To the east of 100degree west
meridian, where there is high
rainfall,the grasslands are extensively
cleared for the cultivation of
wheat,corn and cotton.
This area is known as the granary of
wheat.

24. AGRICULTURE
The main agricultral area of the
continent is the central plains.
Fertile soil,availability of
water,suitable climate, vast
agricultural
lands,mechanisation,all make
this area ideal for the
advancement in
agriculture.Wheat,corn,oats,bar
ley etc are the major crops.

25. DAIRY FARMING
One of the main occupation of the
North American people.The vast

makes a favourable situation for
the availability of fish.The fishing
centres in the Atlantic are St.Pier
bank,Sable Island bank,Browns
bank and Georges bank.
