Do Scientists Think Earth's Oceans Formed?

The ocean formed billions of years ago.
Most scientists agree that the atmosphere and the ocean accumulated gradually over millions and millions of years with the continual 'degassing' of the Earth's interior. ... As the water drained into the great hollows in the Earth's surface, the primeval ocean came into existence.

Where do scientists think the water came from to form Earth's oceans?

Hydrogen and noble gases from the solar nebula were drawn to the planetary embryo, forming the first atmosphere.

Are oceans Earth science?

The oceans are an important part of Earth: they help to determine the make-up of the air, they help determine the weather and temperature, and they support great amounts of life. The composition of ocean water is unique to its location and depth.
