Desert of Antarctica

3 Locations Cover 20% of the Earth’s land mass Latitudes:
15-28° North and South of the equator

4 Locations

5 Climate Less than 10% rainfall per year Hot Deserts: Cold Deserts:
20 to 25° C Maximum Temperature: 43.5 to 49° C Cold Deserts: Winter: -2 to 4° C Summer: 21 to 26° C Antarctica: -89.2°C to -93.4°C

6 Special Features Desert animals are small Desert plants:
Don’t have to drink at all All the water they need from their food Burrow under ground Nocturnal Desert plants: Hairy leaves

7 Wild Life Hot and Dry Deserts: Cold Deserts: Insects Arachnids
Reptiles Birds Mourning Wheatears Horned Vipers Cold Deserts: Antelope Ground Squirrels Jack Rabbits Kangaroo Rats (etc.)

8 Plants Hot and Dry: Cold Deserts: Minimal plant life No plants
Maybe few grass or moss Lichen Algae

9 Threats to ecosystem Itself Global warming: Dry up watering holes
Increased number of wildflowers (kill shrubs and slow growing trees) Irrigation for agriculture: Increased salt levels in the soil Grazing animals Potassium cyanide used in gold mining Off-road vehicles Oil and gas production Nuclear waste may be dumped in deserts Nuclear testing grounds
