  1. Biome
    Large area characterized by plant/animal life
  2. Biome Requirments
    • Nutrients
    • Water
    • Energy
    • Temperature Change
  3. Ozone Layer
    • Middle atmosphere, or stratosphere
    • Absorbs UV rays from sun
  4. Factors that Influence Climate
    • Earth Curvature/Axis tilt
    • Air currents
    • Ocean Proximity
    • Mountains
  5. Types of Biomes
    • Tundra
    • Terrestrial
    • Desert
    • Grassland
    • Marine
  6. Earth Curvature
    • Curvature and tilt produce seasons through temperature changes
    • The positions of the earth affects how much sun hits the surface
  7. Air Currents
    • Hot water-saturated air rises and looses temperature, and moisture, with height
    • Remain equatorial air is pushed North/South by rising hot air
  8. Ocean Proximity
    • Continents cause ocean currents, which cause wind currents
    • Slower heating/cooling of water causes extreme temperatures in costal regions
  9. Gyres
    Circular ocean currents caused by continents
  10. Mountain Effects
    • As elevation increases, air becomes thin
    • Air cools to pass mountain
    • Loss of moisture causes rain on one side
    • Moisture is regained on opposite side
  11. Rain Shadow
    Dry side of mountain due to warm air absorbing water from land
  12. Terrestrial Biomes
    • Coniferous Forest
    • Rain Forest
    • Deciduous Forest
  13. Coniferous Forest
    Populated with pine tree's known as "Conifers"
  14. Rain Forest Types
    • Tropical
    • Deciduous
  15. Tropical
    Rain forests near the equator
  16. Deciduous
    • Leaves fall off trees annually
    • Receive annual rain fall
  17. Biodiversity
    Number of species
  18. Tropical Scrub Forest
    Shorter more widely spaced trees
  19. Savanna
    Dryer grasslands dominated by vegetation with scattered trees
  20. Desert
    • Biome that receives less than 10 inches of annual rain fall
    • Populated by plants/animals adapted to living with little water
  21. Desertification
    Process of dry land becoming deserts through drought and land misuse
  22. Chaparral
    Costal regions bordering deserts
  23. Grassland
    • Continual grass coverage
    • Trees only found near rivers
  24. Temperate Forest
    Forest of North America
  25. Temperate Deciduous Forest
    Forests of eastern North America
  26. Temperate Rain Forest
    Rain forests of western North America
  27. Tundra
    Vast, extremely cold, and flat arctic regions
  28. Permafrost
    Permanently frozen layer of soil
  29. Marine Biomes
    Biomes of oceans, rivers, lakes, etc.
  30. Freshwater Lakes
    • Collection of water from rain/snow run-offs, ground water seepage, or streams
    • Occurs naturally
    • Consists of 3 zones
  31. Life Zones of Freshwater Lakes
    • Near-shore littoral zone; houses plant life
    • open-water limnetic zone; houses plankton
    • lower profundal zone; no plant life
  32. Lake Types
    • Oligotrophic-contain few nutrients; little life
    • Eutrophic-Abundance of nutrients; support plant life
  33. Stages of Water Travel
    • Source region-mountains collect rain
    • Transition zones- streams become rivers
    • Floodplain-deposit of sediment
    • Estuary-where a river meets the ocean
  34. Wetlands
    When soil is covered/saturated with water
  35. Marine Biome Basic Zones
    • Photic-650'; allow light for photosynthesis
    • Aphotic-36,000'; scarce light, no photosynthesis
  36. Ocean Zones
    • Costal Waters-where land meets ocean
    • Coral Reefs-submerged but support plant/fish life
    • Open Ocean-wave action no longer affects bottom
    • Vent Communities-ocean floor; little/no light for plants
