The name Africa was originally used by the ancient Romans to refer to the northern part of the continent that corresponds to modern-day Tunisia. There are many theories regarding its origin. Africa terra means "land of the Afri" (plural, or "Afer" singular), referring to the Afri tribe, who dwelt in Northern Africa around the area of Carthage.
This is a list of continental landmasses, continents, and continental subregions by population. For statistical convenience, the population of continental landmasses also include the population of their associated islands .
A continent is a large geographical region defined by the continental shelves and the cultures on the continent. [1] In the modern day, there are seven continents. However, there have been more continents throughout history. Vaalbara was the first supercontinent. [2] Europe is the newest continent. [3]
(Definitions of "continents" are a physical and cultural construct dating back centuries, long before the advent or even knowledge of plate tectonics; thus, defining a "continent" falls into the realm of physical and cultural geography (i.e. geopolitics), while continental plate definitions fall under plate tectonics in the realm of geology.)
A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions ...
The outlines of the modern continents and other landmasses are indicated on this map. At the end of the Proterozoic, the supercontinent Pannotia had broken apart into the smaller continents Laurentia, Baltica, Siberia and Gondwana. [153] During periods when continents move apart, more oceanic crust is formed by volcanic activity.
The four continents, plus Australia, added later.. Europeans in the 16th century divided the world into four continents: Africa, America, Asia, and Europe. [1] Each of the four continents was seen to represent its quadrant of the world—Africa in the south, America in the west, Asia in the east, and Europe in the north.
Continents affect the climate of the planet drastically, with supercontinents having a larger, more prevalent influence. Continents modify global wind patterns, control ocean current paths, and have a higher albedo than the oceans. [1] Winds are redirected by mountains, and albedo differences cause shifts in onshore winds.
