Here's a tectonic plate map of the Earth, plates are moving singular chunks chunks of the crust (they contain parts of landmasses that move with them), some of the continents are based off of the tectonic plates, others are based off of being part of the same land mass like Eurasia (since we don't call eastern Russia part of North America, even though it is technically part of the North American tectonic plate).
Tectonic plates in order by total area (top 5):
1. Pacific plate - 103,300,000 km2
2. North American plate - 75,900,000 km2
3. Eurasian plate - 67,800,000 km2
4. African plate - 61,300,000 km2
5. Antarctic plate - 60,900,000 km2
Continents in order by land area (as landmasses):
1. Eurasia (Europe and Asia) - 55,000,000 km2
2. Americas (North, Central, and South) - 42,549,000 km2
Individually (not including sub-continents):
1. Asia - 43,820,000 Km2
2. Africa - 30,370,000 Km2
3. North America - 24,490,000 Km2
4. South America - 17,840,000 Km2
5. Antarctica - 13,720,000 Km2
6. Europe - 10,180,000 Km2
7. Australia - 9,008,500 Km2
Additional information:
The Pacific ocean alone has more surface area than all of Earth's land area combined, 165,000,000 km2, roughly 30% of the Earth total surface area.
I shall fug off back to whence I came now.
