Earth’s Transformation: From Green Marble to Blue Oceans

Exploring Earth’s Colorful Past

Did you know that Earth was once a stunning green marble? Before our planet’s oceans turned blue, they were rich in green hues. This vibrant color came from iron and other elements that shaped the early oceans. These green oceans played a crucial role in the evolution of microbes. They developed unique light-absorbing tools that thrived in the green light of those ancient waters.

Early Earth Oceans

As time passed, significant changes occurred. The vibrant green oceans gradually transformed into the blue we recognize today. This transition not only altered the appearance of our planet but also impacted the life forms that inhabit it. The evolution of microorganisms was pivotal in this process. They adapted to the changing environment, paving the way for diverse ecosystems.
