Groundwater is formed when rain drains into the ground and collects within cracks or pores in the rock (called an aquifer). Groundwater makes up about 17 percent of drinking water in Australia. Once in the aquifer, water moves slowly toward lower level areas and eventually moves from the aquifer to streams and lakes, or is extracted from the ground by wells.
Two-thirds of the Earth’s drinking water is stuck in frozen glaciers and streams. Due to the risks and costs related to moving icebergs, they are not used as a major source of drinking water.
About 95% of Australia’s water supplies come from rivers, lakes, streams and reservoirs. Dams are constructed across rivers to collect and store water. This gives us a more reliable fresh water supply. There are more than 820 large dams in Australia.
The lithosphere is the solid part of the Earth consisting of the Earth’s crust (the thin outer layer of the Earth) and the upper mantle. It does not include lower mantle, the liquid iron core or the Earth’s core.
