Tundra

  1. 1. TUNDRA Nicole Sherpensky, Jasmine Moore, Brooke Oliver, Meagan Toole, Sarah Douglas, Andrea Eam
  2. 2. Location (in N. America) <ul><li>Found approximately 55° to 70° North latitudes </li></ul><ul><li>Circles the North Pole and can be found in Northern part of North America </li></ul><ul><li>Covers about 20% of Earth’s surface </li></ul>
  3. 3. Locations of the Tundra
  4. 4. Climatic Conditions <ul><li>Temperature range </li></ul><ul><ul><li>About -40°F to 55°F </li></ul></ul><ul><li>Average annual temperature </li></ul><ul><ul><li>About -8°F </li></ul></ul><ul><li>Annually receives 6-10 inches of precipitation, mostly in the form of snow </li></ul>
  5. 5. Soils <ul><li>Low in nutrients and minerals </li></ul><ul><li>Essentially becomes permafrost, where the soil is frozen </li></ul><ul><ul><li>Absorption of the precipitation into the ground causes little evaporation, thus, creating permafrost </li></ul></ul><ul><ul><ul><li>Permafrost : essentially frozen soil with a layer of frost topping it </li></ul></ul></ul><ul><li>Overall, the soil is poor, but thick as the permafrost continues to pile up </li></ul>
  6. 6. Dominant Plants <ul><li>Arctic moss </li></ul><ul><li>Bearberry shrub </li></ul><ul><li>Pasque flower </li></ul><ul><li>Other Plants </li></ul><ul><ul><li>Labrador tea </li></ul></ul><ul><ul><li>Cushion plants </li></ul></ul><ul><ul><li>Dwarf willow </li></ul></ul>
  7. 7. Arctic Moss Pasque Flower Bearberry Shrub
  8. 8. Plant Adaptation <ul><li>Grow low to the ground to protect from harsh weather </li></ul><ul><li>Some, like the cushion plants, grow in clumps to protect from cold </li></ul><ul><li>Many are adapted to absorb greater amounts of sunlight at one time </li></ul><ul><li>Some are poisonous, like the Labrador Tea, to keep predators away </li></ul><ul><li>A dense amount of roots ensures growth in the barren soils </li></ul>
  9. 9. Animals <ul><li>Arctic Fox </li></ul><ul><li>Grey Wolf </li></ul><ul><li>Caribou </li></ul><ul><li>Polar Bear </li></ul><ul><li>Snowy Owl </li></ul><ul><li>Musk Ox </li></ul>
  10. 10. Polar Bear Arctic Fox Musk Ox
  11. 11. Animal Adaptations <ul><li>Fur and layers are developed for warmth </li></ul><ul><li>Appearance aides in camouflage </li></ul><ul><li>Arctic Fox </li></ul><ul><ul><li>Ears, legs and muzzle are short to conserve heat </li></ul></ul><ul><ul><li>Adapted to eat almost everything </li></ul></ul><ul><li>Polar bear </li></ul><ul><ul><li>To conserve heat: has a thick layer of blubber, hollow shafts of hair, and short legs and ears </li></ul></ul><ul><ul><ul><li>Hollow hairs reflect light allowing the bear to trap the sun’s infrared heat </li></ul></ul></ul>
  12. 12. Animal Adaptations cont’ <ul><li>Caribou </li></ul><ul><ul><li>Large spreading hooves are adapted to snowy winters and marshy summers </li></ul></ul><ul><ul><li>In very harsh weather, they can lower their metabolic rate and go into hibernation </li></ul></ul><ul><li>Musk Ox </li></ul><ul><ul><li>Thick fur preserves warmth </li></ul></ul><ul><ul><ul><li>During winter, they grow thick undercoats of soft fleece, along with thick overcoats of long straight hair that hangs to the ground </li></ul></ul></ul><ul><ul><li>By May, they shed large amounts of their fur </li></ul></ul>
  13. 13. Danger? <ul><li>Direct human contact rare due to harsh conditions </li></ul><ul><li>Pollution and Global Warming puts Tundra in danger zone </li></ul><ul><ul><li>Polar bears have become endangered </li></ul></ul><ul><ul><li>Increases temperatures put the permafrost at risk of melting </li></ul></ul>
  14. 14. Winter Tundra
  15. 15. Summer Tundra
