when it comes to sand dunes of the Sahara desert and more landforms of joints

This is a form of the Sahara desert
that shows 3 different landforms in which actually make up the Sahara Desert by
whole in just one spot. Mountains are the highest peak above. There is a sand
dune right below the side of the mountain. At the the bottom surface is rock
debris mixed with sand. This is called Regs. Insolation Weathering helped
create the Reg landscape.
