Origin of Continents in the World

Actually what is meant by the theory of Pangea? Pangea theory is a theory which states that millions of years ago all the continents together into one big continent called Pangaea (before finally continent now consists of five continents the fruit). Then for some reason is still not known with certainty, the continents broke out and began to drift in the opposite direction. The theory goes on to say that the continents will continue to drift until they meet again, in different configurations. At believed by some experts that Pangea has one characteristic in common with Antarctica now.

Pangea theory itself is based on the theory Alfred Wegener, a German scientist. In the Year 1920 in the book The Origin of Continents and sea (Die Entstehung und der Kontinente Ozeane), he argues that all the continents were at one time formed a single supercontinent Pangaea, before then end and drifted to its current site. Thus the antiquity of the continent in the URLs a pumice stone that moves because of plate movement at the bottom of this Earth's crust. Pangea began to break her self into continental (mainland) smaller named Laurasia (mainland forming the southern hemisphere, such as Latin America, Africa, India, Antarctica, Australia, New Zealand, New guenea etc.) and Gondwanaland (formed as the American mainland and the northern hemisphere Europe) during the Jurassic period (the time of dinosaurs).

Whereas in the late Cretaceous period continent continent there is the same as what we see today (five continents). At the time of the continent Pangaea was formed, which became continental mainland mainland now has a liaison mainland (continental bridge) which connects the southern parts of the Americas (Latin), Africa, India, Australia and his Antartika.Pertanyaan now is, when the crust of the Earth's crust is constantly moving up today, then how much his speed? okay, so this way, the continent we live now moving very slow (and can not be felt by us who stood above), this continental plate movement plate each year reaches 1.5 inches / year even slower than the growth of our fingernails of his annual . And with this clearly needed to million million years for the mainland of the continent to move away and formed the continents that exist today.

And we unknowingly were now continent continent we have "collide" and its process has lasted for several million years, the mainland African continent has collided with mainland Europe.Italy, Greece and almost all cities in the Mediterranean is part of the African plate groove, and that his movements had been recorded in the last 40 million years (according to geologists).Another sign of movement is the Swiss Alps Mountains and mountains of the Pyrenees have been pushing each other, causing earthquakes that sometimes attack the territory of Greece and Turkey. Australia had predicted nor her future when calculated with the movement of Earth's plates, then Australia will continue to move towards the North until hit Southeast Asia. as well as other continents such as the American continent.

Initial formation of the earth's oceans is also influenced by Pangea. After separation (partition Pangea) is expected to emerge oceans formed 180-200 million years ago, the Atlantic Ocean midway between northwestern Africa and North America and the southwestern Indian Ocean between Africa and Antarctica. So it's possible if this continues to happen, then the earth (continents) we are in the process to become "Pangea" next, since the study did show evidence of proof of that. So less than 250 years the Earth may be out of shape again today so do the research that NASA (Pangea Ultima).

Apart form the Ocean, because his theory was first continent we are connected, then when the continent was divided breaks into the present, also carries a similar volcanic characteristics, such as the formation of "ring of fire" or a circular ring of fire from Peru, Mexico continues to elongate until , along the east coast of America (los angeles), Alaska, Japan, and Piliphina, Indonesia, an archipelago in the Pacific, and ended up in New Zealand
