Appearance of the Earth when ocean water is absorbed

If water in all oceans falls into a 10-meter sewer in the deepest area of ​​the world, Mariana, the face of the Earth will change dramatically.

Graphic video posted on social network Reddit on November 10 predicts the prospect of water from all oceans being sucked down to about 11,000 meters in the Pacific, Live Science reported. This is the product of Ryan Brideau, graphic research student and geospatial analyst at University of New Brunswick, Canada.

In graphic video, the Earth's flat map reveals extended shorelines along the land strips that appeared between continents and archipelagos before the sea depleted. In nearly 3 million years the sea water gradually dried up, the islands and large lands emerged from the ocean.

The process of sprinting in the Pacific, where the Mariana basin is located, extends to the end of the graphic video, while other waters are quickly surrounded by land and stop draining water, according to Brideau.

Brideau explained the first time he envisioned a giant fantasy "knot" in the deepest part of the ocean and what could happen after pulling that block when reading a book by writer Randall Munroe.

Munroe assumed there was a blocking button about 10 meters in diameter that caused seawater to be sucked in and poured into Mars. He estimated that it took hundreds of thousands of years for the water withdrawal process to occur at sea level to "less than one centimeter per day".

Brideau was very excited about the challenge of replicating the graphical version of the model Munroe used to calculate the scenario. He found a graphic video of the ocean withdrawal process created by NASA scientists in 2008, but the team took a major shortcoming when excluding the connection between the oceans, according to Brideau.

"That makes a big difference in difficulty, and I want to know how close I can be to Randall's results , " Brideau said.

Graphic design of this type requires elevation maps of soil structures above and below sea level, along with the location data of all major water bodies on Earth."These data need to be" in the form ", but instead of each pixel of color, they record the height and existence or non-existence of the water , " Brideau said.

The model then estimates the rate of water withdrawal in the oceans, adjusting for changes in the interconnection between the waters as they are isolated by the structure rising from the sea floor and stopping the withdrawal of water, Brideau explained. .

The earth changed dramatically when water on the ocean was depleted.

"The hard part is to calculate the remaining water at each step. You have to figure out which water area in the previous step can be drained and subtracted from the remaining water, but leave the water area unaffected. You also have to subtract any land that begins to rise from the sea, " Brideau said.

"The big mistake that I haven't taken into account is the weather, which could make some waters dry up if their main water supply is the ocean. But in fact, the weather is changing too. very hard to predict, " Brideau said.

Brideau's model describes significant changes in continental coastal lines for the first 200,000 years. At the end of the video, nearly three million years after the blocking button was pulled out, only the Pacific Ocean was still pouring into the sewer. At this time, the frame in the graphic shows a reduction of about 10 meters in the depth of the ocean.
