Over to you …• Watch the video carefully stopping it at key points and
recording the most important information under the following headings
• Importance of water in central Australia• 2 million years underground! • From Gondwana to Australia• The Geology – Clay and silt and Rivers and Sandstone.• Permeable and Impermeable ‘the sponge test’ = Aquifer• Total area of the basin & recharge• Total amount of water in the basin
Use the handouts provided to for annotation purposes.

Terrestrial Pump Simpson Desert, Birdsville sits
over the Great Artesian Basin, which is 2032kms wide and 1450km's long, making it one of the largest underground water supplies on earth. With a surface temperature of 98 degrees Celsius, the water has to be cooled before being supplied for drinking and household use.
