  2. Steppes – Eurasia Prairies – North America Pampas – South America Geographic location

  3. Precipitation average of 20-35 in. • Temperature from -40 F to 100F • Prairie: Temp from 20-70, 10-30 inches • Steppes: 10-20 inches • Pampas: 64 Degrees • Cold winters, dry, hot summers, humidity Climate

  4. Dark and Deep • Fertile upper layers • High in calcium carbonate-good for fertility • Chernozem-phosphorus and ammonia, really fertile. • Loess-windblown silt, sometimes derived from glacial deposits(MS river) soil

  5. Human agricultural use • Low precipitation levels • Fires • Absence of tree cover Limiting Factors

  6. Extra body fat and fur Extreme speed Extensive mucous membranes Broad, flat-topped teeth Color Animal Life – Adaptations

  14. Purple Coneflower stinging nettle

  15. Indian Grass pampas grass

  16. Fragmentation-loss of biodiversity • Dust Storms • Wasteland Buildup Environmental concerns
