The World creation was 20 bilion years ago. It started with a very big explosion, the Big Bang. This explosion involved volcanos, earthquakes,... Now a days, the volcanos and the earthquakes continues, so it means that the world is in continous moviment.

First was created the Solar System, and then the planets will appear. Later, in the Earth, a planet, will appear the continents. Some years ago, the continents are only one, there are only one continent, Pangea. But later, with the Earth movements, the big continent will separate and formate the five continents.

In the Earth there are differents plates, and these can move in diferent direccions. For example, they can colise (a subduction zone), or they can separate...

Finally. appeared the life. The fisrt organism that appear was a bactery. Later, the birds, the animals and the humans will appear. The first bird appeared was from 135 milion years ago.
