Australia is a country where the ethnic background of the people is very diverse. It has initially been settled by the Aborigines, and much later came the European settlers. The Aborigines found themselves in a very bad situation when the European settlers arrived because the Europeans tried multiple methods to wipe them out both culturally and ethnically. The initial estimates about the Aboriginal population in Australia and their number in the present do not differ much, but it only represents around 2.5% of the total population. The population of the Aborigines have been decimated for a couple of centuries so their numbers remained static, while there has been an ever growing population of new settlers which became dominant.
Geothermal heat- to provide energy for process like subduction, melting and metamorphism (to drive plate tectonics)
solar energy- for processes like erosion, weathering and transport
