What it is
A short, wordless-style animation by the channel Algol that reconstructs the movement of Earth's continents across billions of years, from roughly 3.3 billion years ago to the present. The description notes it is a second version with newly animated sections covering several early eras.
Cited in 1 Wikipedia article, including Ur (continent).

The formation and break up of supercontinents have happened throughout Earth's history in almost a cyclical manner. There may have been many others supercontinents before Pangaea and the total number of such is uncertain. The 4 last supercontinents are: Nuna [LINK] (some other people call it Columbia) that was present in the period 2.0–1.8 Ga (billion years ago or 1000 million years ago, if you use the long notation); Rodinia [LINK] that formed around 1.1 Ga and lasted until about 750 Ma; Pannotia [LINK] that lasted 650-560 Ma; and finally, Pangaea. The location of the supercontinents seems to have varied throughout Earth's history and it doesn't seem likely that there was something special

@lousycoder: As John has mentioned in his comment, the continents have always been in a constant state of movement as explained by Continental Drift [LINK] . This video [this video] is good illustration of what is thought to have happened. Because of continental drift & the appearance of disappearance of some land masses it is difficult to determine what sea levels were millions of years ago.

Earth's total land area has increased throughout its history according to this video [this video] . What is the dependence of the total area of continents from time?
