Swift J., The Sahara — 1978 (The World's wild places) (Time-Life books)
Аннотация: The Sahara covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Niger, Western Sahara, Sudan and Tunisia. It covers 9 million square kilometres, amounting to 31% of Africa. If all areas with a mean annual precipitation of less than 250 mm were included, the Sahara would be 11 million square kilometres. It is one of three distinct physiographic provinces of the African massive physiographic division.
