By Christian W.

“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 12.5inches of snow a

month! Wow,

that’s a lot!



Landforms

• There are threedifferent typesof land forms inthe tundra that Ifound out about:

• Iceburgs

• Mountains• Snowdrifts



Polar Bears

• Polar bears live along shoresand on sea ice in the icy cold Arctic. In fall pregnant polar

bears make dens in earth andsnow banks, where they’llstay through the winter andgive birth to one to threecubs. Polar bears primarilyeat seals. Their white coatsare very valuable.



Penguins

• Emperors clump together inhuge, huddled masses. Theytake turns moving to the

inside of the group, wherethey’re protected from the icycold temperatures and wind. As the young penguins grow,adults leave them in groupsof chicks called crèches whilethey leave to fish.



Orcas

• Orcas hunt everything fromfish to walruses—seals, sealions, penguins, squid, sea

turtles, sharks, and evenother kinds of whales.Average-sized orcasmay eat about 500 pounds(227 kilograms) of food aday. Orcas’ teeth are shapedfor ripping and tearing prey.They are also called killer whales.



Lichens

• A lichen looks like one plantbut is made up of twodifferent kinds of plants -

algae and fungi. Some looklike a crust growing onrocks and trees. Some looklike little bushy plants andothers hang from thetrees. Many animals dependon lichens for food.



Cloud Berry

• Another plant found in thearctic is the cloud berry. Itis a flower with five whitepedals and one berry per

stalk. The fruit on it is redwhen not ripe, when it isripe it is soft and orange.The plant has large greenleaves. You can find it inmost parts of the arctic.



Pasque Flower

• The Pasque flower hasseveral stems that rise inchesoff 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 leafcovered in hairs, as is the restof 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 havemountains?”Maybe, butunlikely. It all mattersby how much

precipitation. The rockwould just erode away.

• “Why is the sky cleanerthere than here?”Because there isn’t a

lot of pollutingmachines there.



“How Does Water Play

Into My Biome?”

• Water is part of

my biome

because it iswhat the ice

glaciers ice-

burgs and ice-

caps are madeout of.
