Compare the topography of Africa and Australia?

There are fundamental differences in the relief of Africa and Australia. In Africa, especially in its eastern part, there is a rift valley. Place of divergence of lithospheric plates. There is a very large volcanism and active neotectonic movements, accompanied by frequent earthquakes. In Australia, by contrast, there are no earthquakes at all. This is due to the fact that there are no seismically active zones. There is also no volcanism. The only mountain system is the Great Dividing Range.
