THE TUNDRA
The Tundra
The Tundra is an icy, freezing biome that is
mostly permafrost.
It is the world’s youngest biome.
There is little vegetation (only about 1,700
different species)
There are only 48 species of land mammal in
the Tundra.
It is one of the Earth's major Carbon Dioxide
sinks.
Temperature Range
The Tundra has a very diverse temperature
range. This may be because it is one of the
world’s carbon dioxide sinks.
A Carbon Dioxide sink is a place on Earth that
takes in more Carbon Dioxide than it releases.
The temperature range goes like this:
Summer: 3°C - 16°C
Winter: -70°C – (-56°C)
Total Range: -70°C - 16°C
Yearly Precipitation
The Tundra receives 15-25centimeters of
precipitation including melting snow.
This causes the tundra to have very short
growing seasons.
In the arctic, snow hardly ever falls, but when
it does fall, it stays frozen until the summer.
Where is the Tundra
on a world map?
Polar Bears
Polar Bears have 2 layers of fur.
They have thick layers of blubber that are
about 11.43 centimeters thick.
They have long necks so that they can keep
their heads above water while swimming.
They have partially webbed feet and
lengthy legs, which are adaptations they
use to survive.
Polar Bear’s fur is actually clear. The sun
reflects off of it to make it white.
Snowy Owl
Their hearing is extremely sensitive
Long, pointed, claws help them catch their
prey.
Like humans, owls can see their prey with
both eyes simultaneously.
Its long, broad wings help it glide above the
ground to catch their unsuspecting prey.
Bearberry
Bearberries have leather-like leaves.
They grow near the ground so the wind
doesn’t kill them.
Fine, silk-like hairs grow on the plant to
help it keep warm.
The name “Bearberry” comes from the fact
that they are commonly eaten by arctic
bears.
Arctic Moss
Arctic moss is an aquatic plant that lives at
the bottom of lakes in the Tundra.
When it isn’t growing, it stores nutrients and
energy so that new leaves can grow quickly
the next spring.
They stay out of wind by growing close to the
bottom of the lake.
