Innitially when the suns gravity compressed it enough to ignite it it radiated energy, as the energy emitted slowed down it formed the elements, hydrogen first, the simplest atom. Energy forms matter and hydrogen the simplest atom is the closest matter to the suns energy as the energy precipitates to matter, the further from the sun, the more complex elements are formed.
We, being the right distance from the sun have oxygen and uranium and a whole host of other atoms. The hydrogen combined with oxygen to form water.
Variations in temperature due to rotation and revolution and the worble cause evaporation and condensation

Following the constant bombardment of the surface of the earth around 5 billion years ago the surface was still very hot. As the surface cooled over the next billion or so years the moisture that had been brought to Earth by comets and other celestial bodies began to precipitate out of the cooling atmosphere. For millions of years the cooling surface rock and ever cooling atmosphere contributed to the forming of the oceans.

millions of years ago the earth did not have water on the surface, it was all underneath the ground. Kind of like what they think is going on on Mars. You had some bodies of water, but nothing major like an ocean. Then one day a crack appeared from all the pressure. This crack started to spew water very far into the atmosphere and then dropping back to earth. The crack started a chain reaction and it got bigger and went around the world in a matter of minutes. Any Geologist will tell you about the line that goes around the earth, kinda of like a baseball has stitches. This is how oceans were formed.

The oceans formed from water produced by comets, dust, meteorites, and volcanoes. The oceans generally sit on oceanic crust. Oceanic crust differs from Continental crust in that it is far more dense. It is also much thinner. Since it is thinner and denser it lies at a lower elevation and that is why the oceans generally cover them.

With fault lines and plates this has shaped the land mass. Water is 2/3 of this planet and is increasing with ice melting due to global warming and land erosion.

They formed after the ice age.

From water formed as a by-product of the Earth's volcanic activity.

A huge alien, quarter the size of a planet himself, was bouncing through the galaxy, huge leaps between galaxys... off asteroids and comets, jumping from planet to planet, and landed on our ball of rock called earth, and took a leak, which because of his physical alien nature was pure saltwater.

comets, (big balls of ice) bombarded the early planet. the ice melted and formed oceans

I'll tell you what - that is the lamest bunch of answers I seen in a while!
You'd better do a google search and get some better answers than that before you do your report!
