(Note: atmosphere came first, then oceans, then life, then oxygen in the atmosphere)

I. Formation of the oceans

1. All gases released into atmosphere from Earth including H2O
1. These gases formed the early atmosphere
2. Initial crust temperature=600C (So H2O and other gases stayed gases)
2. The process that should occur
1. Crust cools to below 100C
2. All H2O would have condensed
3. Acid gases would react with igneous crystal minerals to form sediments and initial oceans
4. Original ocean was an extremely hot, salty ocean
3. What is thought to have occurred
1. H2O, CO2, and HCL existed into the oceans
2. Water (at a slow cooling rate) would condense into an early, hot ocean
3. Then HCI would have dissolved into the oceans
4. Early Acid Ocean reacted with crystal minerals, dissolving silica and catious, creating aluminous clay materials to form sediments on ocean floors.
5. Presence of blue green algae in fossil records more than 3 billion years ago prove surface temperature cooled lower than 100C
4. Degassing
1. Most degassing occurred in the beginning, and only a little bit since (degassing=Earth giving off gases with volcanic eruptions)

Oceans are still the same volume and salinity because there is no drastic change in ratios of volatiles released throughout geological timer.
