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
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
3. COLD DESERT
Example: Gobi (Mongolia) Winter cold / summer warm (not hot) – low precip.
DESERT ADAPTATIONS
Desert survivalBeat the heat & Conserve water
DESERT ADAPTATIONSPlants have evolved survival strategies
Drop leaves (dormant), succulent (fleshy), no leaves, spines, tap root, wide shallow roots, wax coating.
DESERT ADAPTATIONS
Animals have own special adaptationsSmall, burrow, come out at night or early
morning, dormant during drought, store water in fat, thick scales, dry feces
