The fossil record indicates that oxygen was released into the ocean before it was released into the atmosphere. What would be a sound explanation?
Question 5 options:
Organisms released oxygen into the ocean until the ocean couldn't absorb anymore, so it was then released into the atmosphere from the ocean
Increases in iron in the ocean from undersea vents prevented oxygen from escaping into the atmosphere
Undersea vents dumped oxygen into the ocean which then released it into the atmosphere
Increasingly diverse life in the oceans led to an abundance of oxygen which drifted into the atmosphere
