SOLAR SYSTEM

Detailed explanation-1: -At this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that we now know as our world ocean. 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.

Detailed explanation-2: -Earth’s Early Atmosphere and Oceans. Volcanic eruptions spewed gases from Earth’s interior to the atmosphere, a process called outgassing that continues today. Most of the gas was carbon dioxide and water vapor. The water vapor condensed to form part of Earth’s oceans as the surface cooled.

Detailed explanation-3: -(4.6 billion years ago) As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere.

Detailed explanation-4: -The Early atmosphere was probably dominated at first by water vapor, which, as the temperature dropped, would rain out and form the oceans.

Detailed explanation-5: -The Pacific Ocean is the oldest ocean in the world with the oldest part of it’s floor dating to around 180 million years. However, the Pacific Ocean is technically much older as it developed from the center of Panthalassa, an ancient ocean that first began forming around 750 million years ago.
