- - - - Limestone is found in the desert which is commonly used in building
      - Phospherite is also found here and is used to make fertiliser
    - - The Indira Gandhi canal has provided more opportunities farming as it has created arable land in the arid desert

    - - Vegetation such as the barrel cactus is adapted to the climate by having
        
        A swollen stem to store water
        
        Spikes - a reduced leaf size to minimise the amount of water lost through transpiration
        
        A thick waxy coating on the stem to reduce water loss
      - Other vegetation such as the Joshua Tree is adapted to the climate by having
        
        Leaves that are shiny and smooth to reflect the sun and keep the plant cooler.
