After photosynthesizing organisms multiplied on Earth’s surface and in the oceans, much of the carbon dioxide was replaced with oxygen.
How were the first oceans formed?
Over vast periods of time, our primitive oceans formed. Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . According to this theory, the ocean formed from the escape of water vapor and other gases from the molten rocks of the Earth to the atmosphere surrounding the cooling planet.
