Scribe Post 9/12/11 - Biomes

Today we:
  • Collected EC Page 62A
  • Discussed new homework- UP 65. This is a biome map of the entire globe and a completed version can be found in the textbook on p 429. Some books might not have the map on this page, so look around that area, or use a credible online map.
  • For the rest of the class we completed the chart on UP 67-68 and watched short videos that described each type. There were 8 biomes: Tundra, Coniferous Forest, Deciduous Forest, Grasslands, Chaparral, Savannah, Desert, and Tropical Rain Forest.
  • Tundra: Long, bitter, cold winters, 0-10 degrees Celsius.
  • Less than 25 cm of precipitation a year, mostly snow
  • Has permafrost layer- Permanently frozen soil
  • Animals include wolves, caribou, polar bears. Snow covered land in winter, but many wildflowers, grasses and small shrubs live in the summer.
  • Coniferous Forest: Cold winters, short wet summers
  • Precipitation: 35-75 cm. mostly snow
  • Soil is nutrient poor and acidic because conifers produce acid
  • Wolves, moose, bears, with somewhat large, cone making, needled evergreens
  • Deciduous Forest: Cold winters, hot summers: -30 to 30 degrees Celsius
  • More precipitation than coniferous, so trees are larger (75-125 cm)
  • Lots of nutrients because of decomposed leaves
  • Cardinals, deer, big, broad leaved trees
  • Grasslands: 5 to 22 degrees Celsius
  • About as much precipitation as a Coniferous Forest (25-75 cm)
  • Soil is enriched by glacial deposits and decaying matter- good for farmland
  • Hawks, gophers, mostly grass with RARE trees
  • Chaparral (Temperate Shrublands): Ocean air provide mild rainy winters, long dry summers
