  • The Thar Desert
    • Location
      • It's located in India, Asia. It is North West of Indian on the border of Pakistan
    • Climate
      • Rainfall is below 240 mm per year
      • The soil is not very fertile
      • Temperatures can reach 53 degrees Celsius
    • Adaptations
      • Plants
        • Xerophytic -Saguaro Cactus
          • Long stems that can store water
          • Shallow, spread out roots so that water can immediately be absorbed from the surface of land
          • Spines (rather than leaves) to decrease the surface area to minimize loss of water through transpiration
          • Large surface area for more photosynthesis - energy
          • Thick, waxy coating on the stem to reduce water loss
          • Spikes to protect it from animals and provide shade
        • Some plants have horizontal root systems, some seeds germinate quickly, some store water in their roots
      • Animals
        • Jerboa Mouse
          • Big ears increases SA to keep it cool
          • Nocturnal to avoid surviving the hot temperatures
          • Large eyes fro nocturnal activity
          • Long back legs for leaping
          • Their fur colour matches their surrounding fro camouflage
          • Strong teeth to eat tough plants
          • Live in burrows underground
          • Long whiskers help them feel their way around in the dark
          • Large tail for balance
        • Camel
          • Hair on back for extra shade
          • Long eyelashes for keeping sand out
          • Humps to store concentrated fat to reduce insulation
          • Tough mouth for thorny plants
          • Large, padded feet to prevent sinking
          • Tail to scare flies away
          • Stomach stores water
