The Seven Continents: Yes, All Those Listed Are Continents

The seven regions you listed—Africa, Antarctica, Asia, Australia, Europe, North America, South America—are all universally recognized as continents.

Definition

A continent is a large, continuous landmass ideally separated by oceans. By this standard, all seven qualify:

• Africa — separated by Mediterranean, Red Sea, Atlantic, Indian Ocean.
• Antarctica — isolated by Southern Ocean.
• Asia — Ural Mountains/Caspian/Black Sea separate from Europe.
• Australia — continental shelf (Sahul) distinct from Asia.
• Europe — cultural/historical continent; geologically a peninsula of Eurasia.
• North America — separated from Asia by Bering Strait.
• South America — connected to North America only by Isthmus of Panama.

Common Confusions

• Oceania vs. Australia: Oceania is a region (Australia + Pacific islands); Australia is the continent.
• Eurasia: Geologically one plate; culturally/historically two continents.
• Subcontinents: India, Arabia, Greenland—large but not continent-scale.

Oceans (for contrast)

Five oceans: Arctic, Atlantic, Indian, Pacific, Southern (Antarctic). They separate the continents.

So: your list is correct. All seven are continents.
