Lesson summary

Students examine the global systems (interactions involving the biosphere, lithosphere, hydrosphere and atmosphere) to see how changes to the global systems can potentially impact on the hydrosphere or water cycle. They look for connections between the carbon cycle ie climate change and how this could impact on water resources. They draw conclusions about the link between climate change and water supply and the time scale over which change might occur.

Learning intentions:

Students will...

understand how the interactions involving the biosphere, hydrosphere and atmosphere influences the availability of water resources
recognise the links between changes to atmosphere (ie greenhouse gasses and climate change) with potential changes in rainfall
Students will develop suggested timescales that might be involved with climate change
propose ways people in Australia will adapt to changes in rainfall patterns and higher evaporation rates.
