The Earth’s surface would completely change if the oceans ceased to exist with the appearance of viaducts and mountain peaks.
The isolated islands were formerly connected to the mainland and the mountain peaks jutted out in what was once the ocean.
Dr. James O’Donoghue, planetary scientist at the Japan Space Agency (JAXA), shared a 4K graphic depicting what the Earth would look like without the sea water. Oceans cover 71% of the Earth’s surface. James’ starting point was a 2008 NASA graphic illustrating all of the surface water being sucked into an imaginary sewer.
Incorporating more recent data, the planetary scientist created a 35x higher resolution graphic that adds data on changes in water availability . The end result is a video showing isolated islands formerly connected to the mainland and jutting mountain peaks in what was once the ocean.
“I was most surprised by the presence of countless viaducts. In the last Ice Age, England connected with Europe, Russia connected with Alaska, Asia connected with Australia. These bridges allow. people migrated without ships. This map helps explain the migration process of mankind in prehistoric times, “ said James.
