  2. Types of Deserts: • Hot and Dry • Cold Deserts • Gobi Desert in Asia • Desert of Antarctica Deserts

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

  4. Locations

  5. Less than 10% rainfall per year • Hot 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 Climate

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

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

  9. 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 Threats to ecosystem
