6. TYPES OF DESERTS
 1. Tropical Deserts:
 Examples: Sahara & Namiba (Africa)
 Hot and dry most of the year/ Cold at night
 Very little precipitation!!!
 Few plants , mostly rocks and sand

7. 2. TEMPERATE DESERTS
 Example: Mojave (Southern California)
 Hot day / Cold at night - also cold in winter
 Little precipitation – more than tropical desert
 Sparse vegetation – shrubs, cacti, low diversity

8. 3. COLD DESERT
 Example: Gobi (Mongolia)
 Winter cold / summer warm (not hot) – low precip.

9. DESERT ADAPTATIONS
Desert survival
 Beat the heat & Conserve water

10. DESERT ADAPTATIONS
Plants have evolved survival strategies
 Drop leaves (dormant), succulent (fleshy), no
leaves, spines, tap root, wide shallow roots, wax
coating.

11. DESERT ADAPTATIONS
Animals have own special adaptations
 Small, burrow, come out at night or early
morning, dormant during drought, store water in
fat, thick scales, dry feces
