Tundra: The Icy Biome
By Christian W.
Block 7
“Where in the world are
we?”
•
•
•
•
Northern Canada
Islands west of Greenland
Northern Europe
Antartica
Tempeture and Weather
• It can get as low
as 7 degrees
and rains up to
12.5 inches of
snow a month!
Wow, that’s a lot!
Landforms
• There are three
different types
of land forms in
the tundra that I
found out about:
• Iceburgs
• Mountains
• Snowdrifts
Polar Bears
• Polar bears live along shores
and on sea ice in the icy cold
Arctic. In fall pregnant polar
bears make dens in earth and
snow banks, where they’ll
stay through the winter and
give birth to one to three
cubs. Polar bears primarily
eat seals. Their white coats
are very valuable.
Penguins
• Emperors clump together in
huge, huddled masses. They
take turns moving to the
inside of the group, where
they’re protected from the icy
cold temperatures and wind.
As the young penguins grow,
adults leave them in groups
of chicks called crèches while
they leave to fish.
Orcas
• Orcas hunt everything from
fish to walruses—seals, sea
lions, penguins, squid, sea
turtles, sharks, and even
other kinds of
whales.Average-sized orcas
may eat about 500 pounds
(227 kilograms) of food a
day. Orcas’ teeth are shaped
for ripping and tearing prey.
They are also called killer
whales.
Lichens
• A lichen looks like one plant
but is made up of two
different kinds of plants algae and fungi. Some look
like a crust growing on
rocks and trees. Some look
like little bushy plants and
others hang from the
trees. Many animals depend
on lichens for food.
Cloud Berry
• Another plant found in the
arctic is the cloud berry. It
is a flower with five white
pedals and one berry per
stalk. The fruit on it is red
when not ripe, when it is
ripe it is soft and orange.
The plant has large green
leaves. You can find it in
most parts of the arctic.
Pasque Flower
• The Pasque flower has
several stems that rise inches
off the ground. On each stem
is one flower with 5 petals.
In the center of the flower is
yellow. Below the flower,
around the stem is a leaf
covered in hairs, as is the rest
of the plant. The fruit juices are
made into a drop of liquid that help
with the eye.
“Tour De Biome
Questions”
• “Do all tundra’s have
mountains?”Maybe, but
unlikely. It all matters
by how much
precipitation. The rock
would just erode away.
• “Why is the sky cleaner
there than here?”
Because there isn’t a
lot of polluting
machines there.
“How Does Water Play
Into My Biome?”
• Water is part of
my biome
because it is
what the ice,
glaciers,iceburgs, and icecaps are made
out of.
