One of the interesting scientific themes is research on 5 seas and 7 continents. The reason is that most people are studying the world's oceans and continents at school but we often find themselves in a conversation where the majority of people do not agree with the exact number of continents and oceans I will find it. Why is researching the mainland and the ocean so important? If you want to understand the earth, you really need to understand the surface of the earth. The majority of the surface is actually covered with water (about 70%). More than 95% of them are in salt water. The surface of the ocean is organized in five different oceans, and the relatively small land surface is organized on seven different continents.

The ocean forms the place where the mainland will divide. However, if a new branch boundary is formed on the continent, the ocean will not grow. It tried to keep expanding but the mainland retreated. Because the density of the continent is small, we push the oceanic crust into the mantle. This process is called diving

Let's start from the beginning. Every continent on the same earth was a huge continent called Pangea once. They all belong to the single world sea (Pantalassa). Because all the seas - and the other smaller seas - are connected through the strait. There is only one case where drift of the continent keeps the ocean closed, so its seawater is separated from the ocean of the world, the seas of the Caspian Sea. Basically, the seas of the world seem to be easily divided by the continents, we call them seas, and we call the continent as well. So today we mark five different seas: Arctic, Atlantic, Pacific, India and South. They are interrelated and gather at some point. The Atlantic Ocean and the Pacific Ocean merge at the cape through the Magellan Cape Cape (only there), and India and the Atlantic Ocean meet at the Cape Agulhas (not Cape of Good Hope).
