Answer:
The term "North Africa" is unspecific. There are 7 countries that form the northern border of the continent (Western Sahara, Morocco, Algeria, Tunisia, Libya, Egypt, and Sudan), a total of 13 geographically north (adding Mauritania, Mali, Niger, Chad, Ethiopia, Eritrea, and Djibouti), and about 35 that are at least partly north of the equator.
