Final answer:
Greenhouse gases warmed the atmosphere during the second atmosphere, causing massive precipitation and the formation of the oceans.
Step-by-step explanation:
The statement is true. Greenhouse gases, such as carbon dioxide and methane, are known to trap heat in the atmosphere, creating a natural greenhouse effect. This warming effect contributed to the formation of the oceans on early Earth through increased precipitation. Over time, water from rain, as well as from comets and asteroids, accumulated to form the oceans. The greenhouse effect continues to play a critical role in maintaining Earth's temperature, but the increased emission of greenhouse gases from human activities has led to global warming and climate change.
