How were the first continents formed?
The first continents were formed by partial melting of an older igneous protolith; however, both the composition of the protolith and its tectonic affinity are controversial. Field and analytical studies suggest that the early continents were formed by partial melting of oceanic crust in primitive subduction zones.

How were continents being arranged?
By about 200 million years ago, this supercontinent began breaking up. Over millions of years, Pangaea separated into pieces that moved away from one another. These pieces slowly assumed their positions as the continent we recognize today.
Why is the world divided into continents?
Earth is around 71 per cent water per cent water and 29 per cent land. In fact, billions of years ago, the seven continents of the world were joined together as a single massive landmass called Pangaea. But thanks to plate tectonics, they gradually broke apart and separated.
How were all the continents together?
About 200 million years ago, all the continents on Earth were actually one huge “supercontinent” surrounded by one enormous ocean. This gigantic continent, called Pangaea , slowly broke apart and spread out to form the continents we know today. All Earth’s continents were once combined in one supercontinent, Pangaea.
