In 1858, Snider-Pellegrini made these two maps. They depict his interpretation of how the American and African continents may once have fit together before becoming separated. Antonio Snider-Pellegrini (1802–1885) was a French geographer and geologist who theorized about the possibility of continental drift , anticipating Wegener's theories ...
The border between North America and South America is at some point on the Darién Mountains watershed that divides along the Colombia–Panama border where the isthmus meets the South American continent (see Darién Gap). Virtually all atlases list Panama as a state falling entirely within North America and/or Central America. [116] [117]
Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere.
An ice cap initially covered most of southern Africa and South America but spread to eventually cover most of the supercontinent, save for northernmost Africa-South America and eastern Australia. Giant lycopod and horsetail forests continued to evolve in tropical Laurasia together with a diversified assemblage of true insects.

In a classic map of the world (with north at the top), the southern ends of the continental landmasses appear to "drip" downward. Continental drip is the observation that southward-pointing landforms are more numerous and prominent than northward-pointing landforms.
Satellite view of Africa 1916 physical map of Africa. The average elevation of the continent approximates closely to 600 m (2,000 ft) above sea level, roughly near to the mean elevation of both North and South America, but considerably less than that of Asia, 950 m (3,120 ft). In contrast with other continents, it is marked by the comparatively ...
