A large part of Morocco is mountainous. The Atlas Mountains are located mainly in the centre and the south of the country. The Rif Mountains are in the north of the country. Both ranges are mainly inhabited by the Berber people. At 446,550 km(172,414 sq mi), Morocco is the fifty-seventh largest country in the world (after Uzbekistan). Algeria borders Morocco to the east and southeast, though the border between the two countries has been closed since 1994.
