NASA amazing animation: Watch All of Earth’s Oceans Drain Away in One Mesmerizing Video

Three fifths of the Earth’s surface are covered with oceans. Life in our pale blue spot is completely dependent on this vast ecosystem, a vital resource for food, water and oxygen.

But the surface of the Earth has changed dramatically over the years, and thanks to science, we have a window to the history of our planet. In 2008, planetary scientist James O’Donoghue, who was working for NASA at the time, but now works for the Japan Aerospace Exploration Agency (JAXA), created a simulation that showed what the Earth’s surface would look like if everyone The world’s oceans drain suddenly. .

As the first 200 feet of seawater disappear, continental shelves slowly reveal themselves. The Bering land bridge, which connects Alaska and Russia, is unearthed. Indonesia extends to mainland Asia, while Papua New Guinea joins Australia. “Each of these links allowed humans to migrate, and when the ice age ended, the water sealed them,” O’Donoghue told Business Insider by email.

The longest mountain range on Earth, the crest of the middle ocean, slowly reveals itself after sea levels drop by 6,500 feet. Eventually, seawater is stripped of the deepest cracks in the earth’s crust until the last drops remain, hidden in the deepest corners of the Mariana Trench.

This new iteration of the video includes a tracker that measures sea level and slows down at the beginning to more easily show how much topography is revealed as the first hundreds of meters are removed. “I slowed the start speed because, surprisingly, there is a lot of underwater landscape instantly revealed in the first tens of meters,” O’Donoghue said.
