File:Draining the Oceans video by NASA.webm
Summary
| Description |
English: Remake of an animation NASA made back in 2008, but at high resolution and with edited timing (https://svs.gsfc.nasa.gov/3487), the previous version was 1024x512 while this one is 3840x2160 (4K). From https://svs.gsfc.nasa.gov/3487:
Three fifths of the Earth's surface is under the ocean, and the ocean floor is as rich in detail as the land surface with which we are familiar. This animation simulates a drop in sea level that gradually reveals this detail. As the sea level drops, the continental shelves appear immediately. They are mostly visible by a depth of 140 meters, except for the Arctic and Antarctic regions, where the shelves are deeper. The mid-ocean ridges start to appear at a depth of 2000 to 3000 meters. By 6000 meters, most of the ocean is drained except for the deep ocean trenches, the deepest of which is the Marianas Trench at a depth of 10,911 meters. Credit for files used:
Українська: Три п'ятих поверхні Землі знаходяться під океаном, і океанічне дно таке ж багате на деталі, як і знайома нам поверхня суші. Ця анімація НАСА імітує падіння рівня моря, яке поступово розкриває ці деталі. Зі зниженням рівня моря спершу з'являються континентальні шельфи. Вони здебільшого знаходяться на глибині до 140 метрів, за винятком арктичних та антарктичних регіонів, де шельфи розташовані глибше. Серединно-океанічні хребти починають з'являтися на глибині від 2000 до 3000 метрів. На глибині 6000 метрів більша частина океану буде "осушена", за винятком глибоких океанічних западин, найглибшою з яких є Маріанський жолоб глибиною 10 994 метрів. |

Slovenščina: Tri petine zemeljske površine pokriva ocean, njegovo dno pa je prav tako bogato razčlenjeno kot nam znana kopenska površina. Ta animacija simulira padec morske gladine, ki postopoma razkriva detajle.
