The concept that the continents once formed a contiguous land mass was hypothesised, with corroborating evidence, by Alfred Wegener, the originator of the scientific theory of continental drift, in three 1912 academic journal articles written in German titled Die Entstehung der Kontinente (The Origin of Continents).

An image of Afro-Eurasia, the largest landmass on Earth. A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably 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 ...
Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0).. This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past.
This map puts all of Earth's land mass in the shape of a chicken. ... 200 million years ago and combined most of dry land on Earth into one giant landmass (according to the BBC), is well known.
According to modern definitions, a supercontinent does not exist today; [1] the closest is the current Afro-Eurasian landmass, which covers approximately 57% of Earth's total land area. The last period in which the continental landmasses were near to one another was 336 to 175 million years ago, forming the supercontinent Pangaea .
It was the first supercontinent to form on Earth, all the continental crust on Earth came together and formed one giant land mass. This land mass was surrounded by an even larger ocean, known as Mirovia. There were about four smaller continents that collided and came together to form Rodinia. This event is called the Grenville Orogeny. This ...
Like most breakups, the separation of continents is not a quick and painless process.. Take the supercontinent Gondwana, for example. Some 180 million years ago, the landmass separated from what ...
This is a list of continental landmasses, continents, and continental subregions by population. For statistical convenience, the populations of continental landmasses also include the populations of their associated islands .
