How were oceans formed in the early atmosphere

The vastness of the ocean, covering over 70% of our planet’s surface, is a defining feature of Earth. Its deep trenches, towering waves, and teeming biodiversity have captivated humanity for millennia.

But how did this immense body of water come to be?

The formation of the ocean is a story billions of years in the making, a complex interplay of geological processes, atmospheric changes, and the very chemical makeup of our planet. Understanding this process is key to understanding Earth’s history and its unique ability to support life.

The Primordial Earth: A Dry Beginning

The journey of the ocean begins with the formation of Earth itself, approximately 4.54 billion years ago.

At this time, the early Earth was far from the habitable blue planet we know today. It was a molten, fiery sphere, bombarded by countless asteroids and meteoroids during the Late Heavy Bombardment. This intense period of impact delivered not only heat but also the very building blocks of our planet, including the raw materials that would eventually contribute to the o
