Plates Boundaries. At the locations where two tectonic plates interact, a boundary between these plates exist. There are three types of boundaries that geologist observe. These boundaries are divergent boundaries, convergent boundaries, and transform boundaries.
There are many more than three deserts in Australia, but the main ones and their location are: Great Victoria Desert (Western Australia): 424,400 km2 (163,900 square miles). Great Sandy Desert (Western Australia): 284,993 km2 (110,036 square miles).
Deserts of Australia. Named deserts of Australia cover 1,371,000 square kilometres (529,000 sq mi), or 18% of the Australian mainland. However, approximately 35% of the Australian continent receives so little rain it is effectively desert. The deserts in Australia are primarily distributed throughout the western plateau and interior lowlands of the continent.
