Earth Continents

Most Welcome Readers...
Today we learn about world continents, as we know there are total 7 continents in the world.
How we can define continents?
"Continent" derives from the Latin terra continēns [terra = “land”, continēns = present participle of the verb contineō = con ‎(“together”) + teneō ‎(“I hold”). The meaning is therefore ‎“land held together” or "connected land". Originally the term "continent" was applied to any area of land, of any size, not separated by water, including islands.

This is the most widely adopted model and it classifies the following seven continents:

• Africa
• Europe
• Asia
• North America
• South America
• Australia (or Oceania)
• Antarctica

There are two variations of the six-continent model:

• the first six-continent model (used mostly in France, Italy, Portugal, Spain, Romania, Greece, and Latin America) groups together North America+South America into the single continent "America" (or "Americas").
• the other six-continent model (mostly used in Russia, Eastern Europe, and Japan) combines together Europe + Asia into the single continent "Eurasia"

5 Continents

This model adopts the criteria of both the six-continent models, resulting in the following 5 continents: Africa, Eurasia, America, Oceania (or Australia), and Antarctica.

An alternative five-continent model is the one adopted, among others, by the Olympic Charter, which excludes Antarctica as uninhabited and lists the following five: Africa, Europe, Asia, America, and Oceania (or Australia).

4 Continents

This would probably be the correct subdivision if we adopted a strict definition of continents, ideally defined as large landmasses separated by water. Furthermore, we should consider "separated" only what is naturally separated, excluding therefore the separations resulting from the artificially made Panama Canal (which separates North and South America) and Suez Canal (which separates Africa from Eurasia).

Under this model, the four continents of the world are: Afro-Eurasia (or Eurafrasia), America, andAustralia (not Oceania, which combines Australia with smaller countries in the Pacific Ocean which are separated by water), and Antarctica.

An alternative four-continent model, introduced at the beginning of the 20th centry, included Europe, Asia, Africa, and America.

Past Continent Models

Prior to the end of the 18th and 19th century, two continents were sometimes recognized: the Old(Europe, Asia, and Africa together) and the New (North and South America).

Regions instead of Continents

The United Nations Statistics Division (which we follow when reporting population statistics on this website) groups countries into macro geographical (continental) regions and geographical sub-regions rather than into continents. This system is referred to as the United Nations Geoscheme.

This classification identifies 6 regions: Asia, Africa, Europe (includes Russia), Latin America and the Caribbean (which includes South America, Central America, and the Caribbean), Northern America, and Oceania.
