gases
an atmosphere containing free oxygen
No, when the Earth first formed it was molten, it had to cool before liquid water could collect in its surface. There is also a thought that Earth's water may not have formed form the initial materials making up the Earth but been delivered to the Earth by comet or asteroids impacting the Earth later.
The main source is formed by sea and oceans.
Compaction over years and fossilization. That's what I learned in ap Earth Science.
oceans would dry

what are three characteristics of earth's ocean
It was about 4 billion years ago, that the Earths oceans formed

According to geologist, the oceans had already started to form by 4 billion years ago. Water remainded a gas because Earth was too hot before the oceaan was formed.
I think its Basin
When the earth formed and then cooled, the water vapor and water froze forming the glaciers. The glaciers later started to melt which formed lakes, rivers, and oceans.
The materials that formed the Earth are in fact OLDER than the Earth, because they were around BEFORE the Earth was formed. The Elements that you are made of were formed inside STARS before the Earth ever existed.
because they formed first along with the layers inside the earth
Technically it's all one ocean, but the oceans formed when comets brought water to the Earth, and that water ran downhill until it collected into the lower areas of the Earth's crust.
The tsunami was not invented; it is a natural occurrence. It has been happening on Earth since the oceans formed.
