What is the geography of your country like? Are there any rivers? Are there any mountains?
I wouldn't say that "geography has///hasn't something" because it is the science that studies the lands etc.
Hence, my suggestion is:
There are no deserts, famous waterfalls, volcanos and rainforests on the territory of Germany.
The geography of Germany hasn't a desert, famous waterfalls or volcanoes and rainforest.
very good !
Thanks a lot!
