Number of continents
There are numerous ways of distinguishing the continents;
| Models | ||||||||
|---|---|---|---|---|---|---|---|---|
 | ||||||||
| 7 continents [2][3][4][5][6][7] |
||||||||
| 6 continents [8][3] |
||||||||
| 6 continents [9][10] |
||||||||
| 5 continents [8][9][10] |
||||||||
| 4 continents [8][9][10] |

The seven-continent model is usually taught in Western Europe, Northern Europe, Central Europe, Southeastern Europe, China and most English-speaking countries. The six-continent combined-Eurasia model is preferred by the geographic community, Russia, Eastern Europe, and Japan. The six-continent combined-America model is taught in Latin America, Iran and some parts of Europe including Iberian Peninsula and Greece. This model may be taught to include only the five inhabited continents (excluding Antarctica)[9][10] — as depicted in the Olympic logo.[11]
The names Oceania or Australasia are sometimes used in place of Australia. For example, the Atlas of Canada names Oceania,[2] as does the model taught in Latin America and Iberia.[12][13]
