ULURU

About: 

• Uluru is also known as Ayers Rock.
  
  
• It is a large sandstone rock formation. It is dominantly composed of coarse-grained arkose (a type of sandstone characterised by an abundance of feldspar) and some conglomerate. Average composition is 50% feldspar, 25–35% quartz and up to 25% rock fragments.
  
  
• It is located in central Australia.
  
  
• It is sacred to the Anangu people, the Aboriginal people of the area.
  
  
• It is listed as a UNESCO World Heritage Site.
  
  
• It is notable for appearing to change colour at different times of the day and year, most notably when it glows red at dawn and sunset.
  
  
• Uluru is an inselberg, literally "island mountain". An inselberg is a prominent isolated residual knob or hill that rises abruptly from and is surrounded by extensive and relatively flat erosion lowlands in a hot, dry region.
  
  
• The remarkable feature of Uluru is its homogeneity and lack of jointing and parting at bedding surfaces, leading to the lack of development of scree slopes and soil. These characteristics led to its survival, while the surrounding rocks were eroded.
