The word tundra
comes from the
Finnish word tunturia
means tree less
plains
The northern hemisphere
region includes arctic
tundra and alpine tundra
The southern hemisphere
region includes Antarctica
Location
Arctic tundra is found around north pole , towards the
north of the taiga belt. It includes vast areas of
northern Russia and Canada
Arctic tundra experiences two seasons
Summer with average
temperature of 3-12
degree centigrade
winter with average
temperature of -34
degree centigrade
Rainy season with
average rainfall of 15
to 20cm average
This phenomenon is called midnight sun
Soil remains permanently
frozen in this region and is
called permafrost
The top layer thaws in
summer months
Few marshes, lakes and
bogs are seen when the
snow melts in summer
Vegetation hardly grows in
this region
Dwarf shrubs GrassesHedges
Mosses Lichens Scattered trees
Caribou(reindeer)
Snowy owlsArctic fox
Arctic hareMusk ox
Polar bears
These animals adapted themselves well to the harsh
climate
Reindeer herding
Uses:
Transportation
Milk
Recently natural oil and uranium have been discovered in arctic
region
They live in permanent homes made of
stone and earth
They have temporary winter hunting lodges
called igloos, made from blocks of snow and ice
They wear seal skin in summer and caribou skin in winter
Dress made of seal skin Dress made of caribou skin
The women wear large tunics to carry their babies
Traditional sled Snow mobiles presently replaced
traditional sleds
Fishing Hunting seals
Hunting walruses
Polar bears live in arctic region
They have a thick layer of white fur to protect from cold and to camouflage
themselves easily
polar bears are good
swimmers
They can live with out
food for many days as they
can store food in their fat
Polar bears can eat up to
68 kg of food
They love to eat ringed
seals, berries and grass
Location
Alpine tundra is found in high altitude regions all over
the world (usually above 10,000 feet altitude)
Large areas of the Tibetan plateau fall with in the alpine
tundra zone
This region is severely cold during winter
Summer with average
temperature of 10
degree centigrade
winter with average
temperature of -12
degree centigrade
It receives average
precipitation of 30cm
in a year.
Soil is well drained unlike
arctic tundra soil
Tall trees do not grow in the
alpine tundra region
because it is very cold and
it has very little rainfall
Small –leafed shrubs Very short treesTussock grass
The plants that are found here are
Mountain goats sheep Elk
Marmots
These are some of the animals that are found in
alpine tundra region
The alpine tundra region is
sparsely populated
Domestication of animals Fishing Mining
location
Antarctica is a region between
south pole and Antarctic circle
Surrounded by water,
It is permanently covered by ice
and it is called largest cold desert
of the world
Coldest driest and
windiest place on the
earth
The coldest
temperature on the
earth, -89 degrees has
been recorded in
Antarctica
Most of Antarctica gets
two inches of snow fall
each year
East Antarctica is colder
than west Antarctica
because of its higher
elevation
Mosses Lichens
It has no plant life except for few mosses and lichens
penguins
seals whales
Gulls
Antarctic
pigeons
Antarctic skua
Antarctica has no permanent human residents due to extreme
weather
However scientific expeditions visit from several countries
some of the countries including India has built research centers in
Antarctica
