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]
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.
Throughout the history of Earth, there have been times when continents collided and formed a supercontinent, which later broke up into new continents. About 1000 to 830 Ma, most continental mass was united in the supercontinent Rodinia.
(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.)
The geography of the continents bordering the Atlantic Ocean was the first evidence suggesting the existence of Pangaea. The seemingly close fit of the coastlines of North and South America with Europe and Africa was remarked on almost as soon as these coasts were charted.
Étienne Geoffroy Saint-Hilaire, also looking at the relationship between animals in India and Madagascar, had suggested a southern continent about two decades before Sclater, but did not give it a name. [6] The acceptance of Darwinism led scientists to seek to trace the diffusion of species from their points of evolutionary origin.
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 ...
