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%.

There are a number of seas such as the Mediterranean, which separates the continent of Africa in the south and the continent of Europe in the north, the Red Sea, the Caribbean Sea, the Baltic Sea and others.
