With the help of NASA video, the scientist reveals what the earth would look like if the oceans were drained


71 percent of the earth's surface is covered with water, and the oceans hold around 96.5 percent of the planet's total water. But have you ever wondered what our blue and green planet would look like if all this water were drained?

Planetary researcher and researcher James O & # 39; Donoghue explains in a remake of a 12-year-old video by the National Aeronautics and Space Administration (NASA) what Earth would look like if all of the water was removed from its face. Fifth of the surface of the planet. The scientist was previously at NASA and is currently working at the Japan Aerospace Exploration Agency (JAXA).

For the new video, O & # 39; Donoghue recorded an animation of a 2008 video created by NASA physicist and animator Horace Mitchell and added several things. He edited the timing and added a tracker to show the amount of water draining off during the animation. It was also created with a high resolution of 3840×2160 (4K) compared to the previous version of 1024×512.

O & # 39; Donoghue said, "Three-fifths of the earth's surface is under the ocean, and the seabed is as detailed as the surface of the land that we are familiar with. This animation simulates a sea level drop that gradually reveals this detail when sea level sinks, the continental shelf appears immediately, mostly visible at a depth of 140 meters, with the exception of the Arctic and Antarctic regions, where the shelf is 2,000 to 3,000 meters deeper, and up to 6,000 meters most of the ocean is drained with Except for the deep ocean trenches, the deepest of which is the Mariana Trench at a depth of 10,911 meters.
