In the U.S., people count seven continents: North America, South America, Europe, Asia, Africa, Australia and Antarctica.
However, this is not worldwide standard, as the number of continents varies from four to seven. In the strictest definition of continent, manmade divisions like the Suez Canal and the Panama Canal don’t count, so Europe, Africa and Asia become Eurafrasia, and there is a single American continent. This model also uses Oceania instead of Australia as a continent.
A more common division in Latin America is to have five continents, with America being together and Antarctica being excluded. In recent years, Antarctica has begun to be included to form six continents. Both of these models use Oceania.
The seven-continent model is mostly used in Anglo-speaking and Germanic-speaking countries as well as India, Pakistan, the Philippines and China.
