There are several hypotheses regarding the origin of the word, some sources state that it comes from the Greek root "aphros" "afros" which in Greek means foam; but the real academy of the Spanish language states that the word Africa comes from the Latin "afrĭcus", another of its meanings is "abbrego" which means mild and humid wind that comes from the southwest and that usually brings rain. Africa is one of the continents with the largest territorial extension, the third to be exact, after Asia and America which are the most extensive, its entire territory occupies an area of about 30,272,922 km2, 22% of the total land mass, with a total of 929 113 444 h, geographically speaking the widest part of the continent measured from the tip of Cape Verde in Senegal, in the west, to Ras Xaafuun in Somalia, in the east, is 7,560 km.
Mount Kilimanjaro at 5,895 m is the highest peak on the continent, with continuous snow, in Tanzania and the lowest point is Lake Assale at 153 m below sea level in Djibouti or Djibouti. Africa also has adjacent islands, with a combined surface area of 621,600 km 2, and its main islands are São Tomé and Príncipe and Bioko in the Gulf of Guinea; Madagascar, Zanzibar, Pemba, Mauritius, Reunion (overseas department of France), Seychelles and Comoros in the Indian Ocean; and the islands of Cape Verde, the Canary Islands (Spain) and Madeira (Portugal) in the North Atlantic. This continent delimits by the north with the Mediterranean Sea separating it from Europe; to the east with the Indian Ocean and the Red Sea, remaining joined to Asia by the small Isthmus of Suez;to the west by the Atlantic Ocean; to the south with the Atlantic Ocean and the Indian Ocean. Demographically, Africa occupies a quarter of the total land area with only 5% of the population, its total population is 765,800,000, with an average density of eighteen people per square kilometer.
As for the history of Africa, it is argued that it is the cradle of humanity, where the species of hominids and anthropoids that gave rise to human beings descend; the hypothesis expresses that in this place Homo sapiens emanates around 190,000 years and then spread to the rest of the continents.
