Sand dunes zigzag across the Sahara Desert in the Tiris Zemmour Region of Mauritania. Since the majority of Mauritania is covered by desert, temporary dune ranges like those in this Overview can form, disappear and reform as sands shift. Average rainfall in Tiris Zemmour is around 3.9 inches (100mm) per year.
