Continental sift theory
It states that all the continents were once a single supercontinent and broke up and drifted to their current locations.
The largest single landmass on Earth is Afroeurasia (the continents of Africa, Europe, and Asia). It occupies 85,000,000 km2, or about 5 times the size of Russia.
The theory of continental drift did originate in the 1930s. Continental drift asserts that the continents were once a single landmass called Pangaea that drifted apart over time.
The Theory of Plate Tectonics, Continental Drift states that there were previously Gondwana and Laurasia as named.The two continents eventually merged to the single mass, Pangaea, and then broke apart after coming together in subduction, to expand and "Drift"
That there was once a super continent called Pangaea huge land mass was broken into continents that drifted apart. The theory also suggests that the earth is made up of 7 gigantic shifting slabs of the earth's crust. This disproved the more popular (at the time) "raisin" theorem
Continental Drift theory (:
The continents used to all form the supercontinent of Pangea. The theory of continental drift explains how they separated and formed today.

this supercontinent is called PANGEA. it is the greek word for "all lands".
If put together, they would fit perfectly into one huge super continent like a puzzle.

The theory that all present continents were once joined together in a supercontinent called Pangaea was proposed by Alfred Wegener in 1912. He suggested that over time, Pangaea broke apart into the continents we see today, a process known as continental drift.
