Most of the people must be aware of these 7 continents – Africa, South America, North America, Asia, Europe, Australia and Antarctica. But, only few would be there who were aware of the formation of these continents. Not just this, but they were also be unaware of ages of these continents. Like earth’s formation, predictions have also been made about the formation of continents. If anyone wants to know completely about Earth or life’s origin, he/she needs to know about continent’s formation. So, in this article, I had shared complete information as how and when were the continents formed.
What Lead to Continents Formation?
It is certainly a difficult question. Because there is no one who can explain the particular reason as how and why continents formed. But, there are many theories that explain a little about this reason. The theories have been illustrated after watching the fossils that are found below the earth’s crust. Below, I have shared the order in which different things evolved on Earth:
The Earth’s Formation – Not only Earth but all the planets are formed by the same process. According to researchers, about 4.6 billion years ago, there was only a ball of burning gas. It was revolving and spinning through space. It was assumed that this spinning ball is the sun. This ball is composed of several gases, dust, and other rock particles. Due to two gases –Helium and Hydrogen, there occurs fusion process called nuclear fusion. In nuclear fusion, a bigger particle splits into two or three smaller particles. Here, the hot ball called sun broke into various articles producing heat, light and radiations. In this way, all the eight planets formed including our mother earth. The necessary things water and oxygen were also founded and life evolved on this planet.
The Continent’s Formation – After formation of Earth, there started another process that paved the way for continents and oceans. Firstly, after 100 million years, land masses emerged into oceans. And after another 250 million years, the formation of continents was started. In the process, all contents that were present at that time formed into a super-continent known as Pangaea. Then, after 200 million years, this super-continent was split into two more continents called Laurasia and Gondwana. The continents such as South America, Australia, Africa and Antartica that you know today were formed from this Gondwana. Then, the Indian sub-continent also broke away and led to the formation of world’s tallest mountain range called the Himalayas.
Formation of Different Continents – Many big land masses called rocks and small landmasses called cratons formed into various continents. One continent called Vaalbara supercontinent was formed. This massive continent got its name from two words – Kaapval and Pilbara. Antarctica continent was formed around 2.52 billion years ago. The Kenorland continent, the Greenland, and Wyoming cratons lead to the development of this continent. Next, Atlantica continent was formed around 2 billion years ago. It was made through cratons that are located in Northeastern South America and West & Central Africa. This is the part which is now known by the Atlantic Ocean. A similar process led to the formation of other continents. Now, we only know what are the 5 oceans and 7 specific continents. But, in earlier times, there might be some other continents that would have emerged and buried deep into the seas and oceans. So, it is difficult to know all things about continent’s formation
The Future of Continents – Do you know the future of continents? Exactly, uncertainty prevails about this statement too. According to scientists, the 7 continents that we know today would converge again and would form a new, massive supercontinent.
It is important to know how our 7 continents evolved. Many scientists had proposed several theories about the formation of continents. The earth was formed around 4.6 billion years ago. It was the fusion process that leads to the evolution of all 7 planets. Around 250 million years ago, rocks, landmasses, and crators formed into a super-continent known as Pangaea. This super continent then evolved into Laurasia and Gondwana. And finally, these continents led to a formation of our modern day continents like Antartica, South America, and Europe. The future of continents is still uncertain, and these can gain form a super-continent. These are the basic processes that evolved our 7 particular continents.
