There are several models for the continents:
Physical models:
Four-continent model (Eurafrasia, America, Australia and Antarctica)
Five-continent model (Eurasia, Africa, America, Australia and Antarctica)
Six-continent model (Eurasia, Africa, North America, South America, Australia and Antarctica)
Political models:
Six-continent model (Europe, Asia, Africa, America, Oceania and Antarctica)
Seven-continent model (Europe, Asia, Africa, North America, South America, Oceania and Antarctica)
Eight-continent model (Europe, Asia, Africa, North America, Central America, South America, Oceania and Antarctica)
OBS:
"Eurasia" is a combination for Europe with Asia, because there is no ocean that separates these continents.
"Eurafrasia" is another combination, for Europe, Asia and Africa, because Asia and Africa are separated by a canal (the Suez Canal), not a ocean.
