YouTube clip on how the Earth was made
- 4.5 billion years ago the sun was surrounded by a cloud of dust
- the dust cloud cooled and formed minerals
- the minerals began to clump together, held together by static electricity
- minerals stick together to make rocks and then the rocks stick together to make boulders then the boulders stick together and eventually it will form a plane
- 30 millions year later after rocks/minerals forming together, the Earth was made
- then the earth melted into a big ball of lava
- all the metals sank, and all the rocks floated
- the outside cooled and formed the crust of Earth
- then another planet crashed into Earth
- all the rocks blown into space were collected together to make the Moon
- every time a meteorite hit the forming earth, it bought a little drop of water to earth
- after years and years, billions of meteorites formed the oceans and rivers
- a meteorite crashes into earth and it contains a chemical called an Amino Acid
- the Amino Acid formed long chains and is now called protein
- protein can replicate them self and when it replicates them self we call it DNA
- DNA made bacteria
- bacteria breathed out there own gas called oxygen
