How might the oceans on early earth have formed?

It's believed that the early oceans were formed by water vapor that originated from volcanos.

Water vapor raised from the volcanos into the air.

As the water vapor cooled, clouds in the atmosphere formed.

Eventually it rained causing flooding, and designing, creating the large bodies of water we know today.

Even though the ocean doesn't look like what it did millions of years ago, it's still the same water

That being said, water vapor from volcanos is the reason why we have oceans.

The Answer You Are Looking For Is

A) Water Vapor Came Out Of Volcanoes

Explanation: I took the quiz for myself. I got a 5/5

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
