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).
Some deserts, however, are located on the west coasts of continents, such as the Namib in Africa, or the Atacama in Chile, forming coastal fog-deserts whose aridity is the result of cold oceanic currents.The deserts of the world occur in six global bio-geographical realms:frotropic deserts are found in the sub-Saharan part of Africa, and in the southern fringe of the Arabian Peninsula. Pressures on the ecosystem from humans are relatively high, especially in the Horn of Africa and Madagascar.
