General Description - Location
 Located on in the
Northern Hemisphere
 Covers about 1/5 of
the Earths land surface
 Arctic Tundra is a
place of barren land,
that sometimes is
grassland
 The sun barely shines
in the winter and
almost never sets in
the Summer because
of the Earth’s Tilt
General Description Temperature
 Temperature is
always cold –
Never reaches
above 25 degrees
Celsius

Polar Bears and the Arctic Wolf are the top predators
Food Web
Primary Photosynthesizes: Arctic Moss,
Bearberry, Caribou Moss, Diamond-leaf
Willow
Who Eats the Plants: (Herbivores) Musk
Ox, Arctic Hare, Lemmings, Caribou, and
Pikas
Who eats the animals that eat the
plants: (Carnivores) Arctic Fox eat the
Pikas along with the Lemmings. Snowy
Owl, Coyotes and River Otters.
Who is a carnivore: (Scavenger) (eats
anything) Ermine, Arctic Fox and
Wolverines. Wolverines may be small but
they are very strong. They can catch
animals that are much bigger than
themselves to eat.
Top Predator: Arctic wolf and the polar
Bear along with Arctic Fox along with
Coyotes.
Adaptations
Ermine: It’s claws allow it to dig easily into the ground. The coat of the Ermine
changes with the seasons to camouflage it from its predators
Polar Bear: Has two layers fur to keep it warm in the harsh climate
Caribou: has large spreading hooves to support them in the snow in the winter
and the marshy tundra in the summer.
More Animal Adaptations
 Snowy Owl: Dense white feathers to keep them warm and
also to provide camouflage in the snow
 Rock Ptarmigan: seasonally camouflaged to prevent it from
being attacked by predators.
Plant Adaptations
 Bearberry: Low growing plant that can stay out of wind chill
and also has leathery leaves to protect it from the cold
Geological Feature
Permafrost
 Ground that is frozen for at least two
years
 Is formed when water is frozen within
the ground
 Permafrost can reshape the land
thought slight thawing and freezing
 Can stay frozen all summer long
A jackhammer must
be used to dig into
the soil
Process when melting
The sun heats the
topsoil, but is not
hot enough to heat
up permanently
frozen ground. As a
result there are
massive swamplands
that slosh above the
frozen ground.
