Deserts: Africa has many vast deserts, including the largest hot desert in the world, the Sahara. The Sahara Desert is located in northern Africa and covers 3,500,000 square miles (9,065,000 square kilometers). The Kalahari, in southern Africa, is another large desert. Islands: The biggest island off Africa is Madagascar, which is near the coast of southeast Africa. Madagascar covers 226,658 square miles (587,000 square kilometers). Other islands include the Seychelles (a chain of islands north of Madagascar), the Comoros (another chain of islands north of Madagascar), the Canary Islands (a chain of islands off the northwest coast), the Madeira Islands (another chain of islands off the northwest coast), the Cape Verde Islands (off the coast of western Africa), Equatorial Guinea (off the coast of Cameroon), and Sao Tome (southwest of Equatorial Guinea).

The boundaries of the Sahara are the Atlantic Ocean on the west, the Atlas Mountains and the Mediterranean Sea on the north, the Red Sea and Egypt on the east, and the Sudan and the valley of the Niger River on the south. Sahara is divided into western Sahara, the central Ahaggar Mountains, the Tibesti massif (a region of desert mountains and high plateaus), and the Libyan desert (the most arid region).

The name "diamond" comes from the Greek "adamas," meaning unconquerable. Made of pure carbon, diamonds are the hardest natural substance known to man. Diamonds were formed in the depths of the earth and are three quarters of the earth's age—although humans didn't find them until 4,000 years ago. Put another way, if the earth's age was on a twenty-four hour cycle, diamonds would be born in the first hours of the morning, but man didn't find them until seconds before midnight.
