GENESIS

Aproximatly sis billion years ago, the Earth borned. The Earth was originated by a supernova explosion, and the gravity formed our solar system with all the planets, asteroids and stars in a small point of space.
Lots of earthquakes and volcanoes which expulsed lots of molten earth formed, when that got cold, an only continent called Pangaea. Some rifts and moviments of the Earth, formed the oceans: for exemple the Atlantic ocean was formed by a rift between Africa and America.
Million years took the Earth to separated in continents as that are as nowadays : Africa, America, Europe, Antartica and Australia.
Mountains appeared when tectonic plates crushed and the fauna, and obiously the flora came up.
The Earth is always in a continue change, because some subduction process modify the litosfere but nowadays we can know when this changes will be produced, because we have got a lot of tecnology and also studies to predict them.
