Landmass

Short description: Large area of land

A landmass, or land mass, is a large region or area of land that is in one piece and not broken up by oceans.[1][2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island.[3][4] In the field of geology, a landmass is a defined section of continental crust extending above sea level.[5]

Continents are often thought of as distinct landmasses and may include any islands that are part of the associated continental shelf. When multiple continents form a single contiguous land connection, the connected continents may be viewed as a single landmass. Earth's largest landmasses are (starting with largest):[6][7][8]

1. Afro-Eurasia (main landmass of the geoscheme region of the same name and its continental parts Africa and Eurasia \- or Europe and Asia; the center of Earth's land hemisphere, comprising more than half of Earth's landmass)
2. Americas (main landmass of the geo-region of the same name and its continental parts North and South America; comprising most of the landmass of the Western Hemisphere)
3. Antarctica (main landmass of the geo-region and continent of the same name)
4. Mainland Australia (main landmass of the geo-region Oceania, its sub-region Australasia, the continent Australia and the country Australia )
