MARGINREGIONIt is located to the east of the greatlakes and the
Appalachianmountains.Due to the influence of the ColdLabrador
Current in the westwinters are very cold.Rain is experienced here
insummers.In south the summersare very hot and winters aremild.The
coastal regionexperiences cyclonic winds likeHurricane and Tornado.
13. COOL TEMPERATE WESTERNMARGINIt extends from the north
ofCalifornia to Alaska.The warm Alaska currentthat flows through
theseshores make the summershot and winters cool.The proximity to
the rockymountains helps in ensuringheavy rain fall in the
region.Coniferous forests aremostly found here. 14. THE PRAIRIE
GRASLANDSIt extends from the south of Taiga,the region between the
Great lakesand the rockies, to the missourimississippibasin.Short
grass is the vegetation seenhere.To the east of 100degree
westmeridian, where there is highrainfall,the grasslands are
extensivelycleared for the cultivation ofwheat,corn and cotton.This
area is known as the granary ofwheat.GRASSLANDSOF NORTH AMERICA 15.

area of thecontinent is the central plains.Fertile
soil,availability ofwater,suitable climate,
vastagriculturallands,mechanisation,all makethis area ideal for
theadvancement inagriculture.Wheat,corn,oats,barley etc are the
major crops. 20. DAIRY FARMINGOne of the main occupation of
theNorth American people.The vastgrasslands here is conducive
torearing cattle.In the north easternparts of the United States
ofAmerica and in the adjacentregions of Canada,it is seen on alarge
scale.In the dry areas of therockies, sheep are reared forwool and
meat, pigs for meat,fowl for meat and eggs.DAIRYDAIRY FARM 21.
FISHINGNorth America has oceans onthree sides.In the shallower
areas of thePacific and the Atlantic oceans alot of plankton is
seen,whichmakes a favourable situation forthe availability of
fish.The fishingcentres in the Atlantic are St.Pierbank,Sable
Island bank,Brownsbank and Georges bank.FISHING 22. INDUSTRYThe
large deposits of minerals and oresespecially those which are
energyresources, and the availability ofagricultural and forest
products havehelped America in industrial development.The
willingness of the American peopleto work hard and their
entrepreneurialinclinations are reasons flourishingindustries. 23.
