The River Nile separates North Sudan into a west and east part. While west of River Nile the part is called the Libyan Desert, east of Nile the part is called the Nubian Desert. However, the north part of Sudan belongs to the Sahara desert.
The Nubian Desert has a very arid climate. The landscape is mostly flat and rocky. Hills of lava stone from early volcanic activities are visible.
The vegetation is very rare, only some trees and little grass that’s all.
