3 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.

4 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.

5 Management of GAB - AUS Make some revision notes based on the video on the previous slide. Include details of how water has been traditionally extracted from deep under the surface.
