THE FORMATION OF CONTINENTS AND OCEANS

Diposkan oleh Rosmana A.P. Saturday, July 25, 2009

Earth was created around 4 milliard years ago. At that time, Earth still a giant hot gases planet. There isn't any land, sea, even living thing. There's only hot magma everywhere.

This condition never change until around 500 million years after Earth's born. After 500 million years after Earth's born, the "liquid rocks" and magma on Earth start become harden. After the harding process, suddenly carbon dioxide and water vapor go away from the inner part of Earth and form thick giant cloud which covers all of the Earth surface and downpour the first rain which will end thousand years after that.


This first rain is believed as the longest time rain ever fall. This is because water will evaporate rapidly when it reach Earth surface due the extremely high temperature. This is the cause of why Earth become cooler than when it was a hot planet.

Thousand years after the first rain start, it suddenly stop. This is because Earth has become cooler than before. The appearance of Earth surface also changes. This rain not only cool down Earth surface temperature, but also it's surface appearance which has become a giant ocean that surrounds the largest continent ever formed, "Pangaea".

Pangaea is the largest continent ever formed. Pangaea is the origin of five continents which are known now. This is because Pangaea consist of these five continents which were connected at that time.

Based on "The Continental Drift Theory", the formation of five continents starts from the break of Pangaea. This break was cause by the move of tectonic plates in Earth. These tectonic plates move slowly (around 3 until 5 centimeters per year). But, this move has break Pangaea into two smaller continents, Laurasia and Gondwana only in millions years time

Then, more breaks are happened. Long after that, these continent become the continents which we know now. At the first time, there isn't any evidence. Long time after that, an evidence was found. Fossils record shows that there're three kind of stegosaurs in three continents, Stegosaur (America), Huayangusaur (Asia), and Kentrosaur (Africa). These stegosaurs fossils shows that these stegosaur are almost similar. But how they can be scattered so far? Maybe it because these dinosaurs migrate from one place to another when the continents are connected each other (Pangaea). Beside that, some of each continents's coastline show similarities. This coastline shows that these continents are connected each other and form The Super-Continent Pangaea.
