"The desert is under black volcanic lava layers, which is the prime cause of
such an extreme climatic condition," says Parviz Kardovani, professor of
geography at Tehran University.
Kardovani believes that being lowland is another cause of the desert's
extremely hot and dry weather.
"The desert's hot weather has left no possibility for life - even bacterial
life. A dead animal in the desert will not decompose; it will rather get
dried by the searing heat from the sun," the professor added.
