Answer:
A landmass is a big area of land.
Explanation:
While there different definitions of what constitutes a landmass and what is only a piece of land, accepted consensus is that a landmass is a very large area of land that is not broken up by oceans.
Australia, for example, is a continent, but it is also a landmass. Asia, too is a landmass that is connected to other landmasses such as the European and African continents.
Landmasses can also be smaller. Greenland, for example, is much smaller than Australia and is considered an island, not a continent. But, it is a landmass.
