Continents of the world

 

Millions of years ago, the world was not in its current form, which consists of a number of continents, oceans and seas

- Perhaps you have heard a lot of scientific theories that talked about the emergence of continents and their displacement, such as the theory of Wagnertree, which says that the world was in the past a single continent, which he called the continent of Bengaia, surrounded by a huge ocean called the Great Ocean or Oceanus.

This continent broke into blocks and moved away from each other during a very long period of time, so the continents formed in their current form and the areas separating them turned into seas and oceans.

Earth's area (land + water) is 510 million square kilometers

Seas and oceans cover about 71% of the Earth's area, while the continents (land) occupy the remaining 29%.
