Actually the original "supercontinent Pangaea" is thought to have eventurally divided into the continents we have today which is 7.
The Pangaea theory is one that states that all present continents were once together and collectively known as a 'supercontinent' called a Pangaea. The word 'Pangaea' means 'all lands' in Greek, accurately defining the way the continents were 180-200 millions years ago before it split up. During the Jurassic Period, it first split into two supercontinents; Gondwana (originally named Gondwanaland) to the south and Laurasia to the north. These pieces then drifted slowly apart and became the continents of today.
Even until now, the shape of the Earth surface is still changing, and it will be forever, as long as the mantle underneath the Earth's crust gets heated and convection currents in the magma keeps dragging the plates.

Plate Tectonics - Pangaea Continent Maps Plate tectonics is the study of the lithosphere, the outer part of the earth jointly with the crust and part of the better mantle. The lithosphere is split right into a pair of dozen great plates which circulate and have interaction with one yet another to create earthquakes, mountain ranges, volcanic activity, ocean trenches and various of different different helpful aspects. Continents and ocean foundation are moved and adjusted in shape as a effect of those plate strikes. The sequence of maps below instruct how a great supercontinent, called Pangaea grow to be fragmented into a number of products, each and each being part of a cellular plate of the lithosphere. those products have been to grow to be Earth's present day continents. The time sequence instruct interior the path of the maps lines the trails of the continents to their present day positions..

Pangaea or Pangea (derived from Παγγαία, Greek meaning 'all earth') is the name given to the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago, before the process of plate tectonics separated each of the component continents into their current configuration.

Laurasia and Gondwanaland.
Laurasia consisted of the most of modern north America, North western Eurasia, Siberia, most of modern Central Asia, North China and East China
Gondwanaland consisted of Antarctica, South America, Africa, Madagascar, Australia, New Guinea, New Zealand, the Indian Subcontinent and Arabia.
