If you are speaking of 'continent lands' above sea level, you might loosely say there are really only 4 very large land masses on earth:
You have the combined joined 'continents' of Asia, Europe and Africa, which, in truth, are really all one land - a joined, continuous mass of land. You also have the continuous land mass of North and South America; there is also Australia; and the 4th very large mass might be Antarctica.
Of course, there are some other quite large land masses above sea level, as well, such as Greenland, Iceland, New Guinea, Madagascar, etc
However, by name, the largest single land mass is called, "Asia".
The largest political country is Russia.
The largest bodies of land on earth are called continents and there are a total of seven on the earth.
The continents are earth's largest bodies of land. The oceans are the Earth's largest bodies of water.
The largest communities on land are called cities if they are related to human communities. On the earth, the largest communities are called biomes.
In general, we call the largest areas of land on earth the continents of the earth.
