The correct answer is - Atlas Mountains.
The Atlas Mountains are the highest mountain range in Northern Africa. They are located alongside the northwestern part of the continent on the territories of Morocco, Algeria, and little part in Tunisia.
This mountain range borders the Sahara Desert on the south, and the Mediterranean Sea and the Atlantic Ocean on its north, with the Strait of Gibraltar also being in the middle.
The Atlas mountains are formed in the Alpine orogenesis, and the land started lifting up because of the collision between the Africa and Eurasian plates, a process that still continues in the present.
