CLIMATE+AND+GEOGRAPHIC+FACTORS+INDIGENOUS

**__ CLIMATE AND GEOGRAPHIC FACTORS __**  -Present day Australian climate was established approximately 10 000 years ago. Prior to this, the areas were supposedly more humid with larger animals [|**] - Some 20 000 years ago the last great ice age came about [|**] - Due to floods that later came, Tasmania had been isolated and therefore missed out on various inventions such as the spear thrower and later advances in stone technology. [|**] - Also due to floods, 'land bridges' had been covered and isolated those who migrated to Australia after being shut off from the New Guinea- Australian bridge, also limiting their exposure to advances in technology.

Present Day Climate-

- South east corner of Mainland and Tasmania = coldest - Geography varies depending on location (Australian alps = snow, colder, also has large deserts, tropical/temperate forest) [|**] - 40% landmass covered by dunes [|**] - Southeast & southwest corners = temperate climate [|**] - Northern part = tropical [|**] - Sometimes dust storms in certain regions [|**] - 80% less than 600 millimeters of rain per year. [|**] - 50% less than 300 millimeters a year [|**]

__HAZARDS__ [|**] - Ocassional tornados - Dust storms - Cyclones on northern coast - Severe thunderstorms - Frequent bushfires - Droughts

__SEASONS__ [|**] - Fall - March-May - Winter- June- August - Spring- September - November
 * -** Summer - December- February
