1
AUSTRALIA’S NATURAL RESOURCES
2
Natural resources are things supplied by nature that can be used by humans They include water, soil, forests, fish, energy, mineral deposits and wildlife/natural scenery Australia has more natural resources per person than any other country The reason for this is that we have a large country but a small population Australia is the world’s largest coal exporter
3
RENEWABLE ENERGY Global warming and increased greenhouse gas emissions has prompted more research into renewable energy Some types of renewable energy that work/may work in Australia are: Geothermal energy: water is heated by pumping it through underground “hot rocks”. This results in steam that drives an electricity generating turbine. Wind power: a wind turbine can power up to one thousand homes Tidal power: waves drive electricity producing turbines (very suitable for desalination plants)
4
RENEWABLE ENERGY Biomass energy: combustion of organic material used to produce electricity and liquid fuels such as ethanol Solar power: technologies that harness the heat and light of the sun to provide heating, lighting and electricity Hydro-electric power: the use of artificial dams (e.g. Snowy Mountains Hydro-electric scheme) to produce energy Often renewable energy isn’t used because it’s too expensive, policies like the carbon tax will bridge the gap and make it just as expensive to use non-renewable resources e.g. fossil fuels
5
MINERALS Australia is rich in mineral resources Pilbara Region, WA: some of the largest iron ore reserves in the world Weipa, QLD/Gove Peninsula, NT: large reserves of bauxite and aluminium Additionally there are other minerals such as silver, copper, nickel and tin The main goldfields are in WA
6
MINERALS Australia is: The world’s largest exporter of iron ore, bauxite, lead, diamonds, zinc ores and mineral sands The world’s second largest exporter of alumina The world’s third largest exporter of gold
7
SOILS Because of low rainfall and poor soils much of Australia is not very useable for agriculture Most parts of Australia are only suitable for sheep and cattle grazing There are some patches of good soil including soils formed on rock of volcanic origin Darling Downs, QLD Orange, NSW Clarence River, NSW Margaret River, WA

NATURAL SCENERY Australia has unique flora and fauna and general scenery attracting many tourists Australia has many sites listed on the World Heritage List Kakadu National Park – natural (e.g. biological diversity) and cultural (e.g. Aboriginal art) significance Fraser Island Great Barrier Reef Blue Mountains
9
FORESTS Apart from Antarctica, Australia is the world’s least forested continent Woodland and shrubland is the predominant vegetation in Australia Before European settlement 9% of Australia was forested, presently only 5% is forested Australia exports some timber and timber products, however large amounts of timber have to be imported particularly softwoods
