Imagine a world where the oceans all dried upwardly, leaving only dry out land backside. NASA reveals a remarkable video showing what Globe would look like if the oceans tuckered.

The video beneath is a remake of the 2008 blitheness past Horace Mitchell from NASA. In 2008, Dr. Mitchell adult an animated video showing a scenario where iii-fifths of World'due south surface, which is currently under the ocean, was revealed.

The video was recently remade by Dr. James O'Donoghue, a planetary scientist with Japan Aerospace Exploration Agency and formerly with NASA. Dr. O'Donoghue recreated the video at a much higher resolution, slowed down the blitheness to amend see what the Globe looks like during the showtime 10's of meters of draining and added a tracker to show how much water had been tuckered.

The video reveals important information most the vast unknown of the ocean seafloor but as well nigh human being evolution.

During the last glacial maximum (LGM), about 26,000 to 19,000 years agone, sea level was about 410 feet below its current level. The sea level was and then much lower than it is today because a tremendous corporeality of the bounding main's h2o was locked away on meridian of continents and countries across the world, from Antarctica to Greenland likewise every bit northern North America and Europe.

This resulted in shallow land bridges appearing betwixt continents and islands. In the early history of humans, these country bridges were used to migrate effectually the world.

Our ancestors migrated from continental Europe to the Britain through land bridges, as well every bit from Alaska to the far eastern tip of Russia. Also, the land connecting North and South America was wider and thus easier to navigate between the two continents.

Beneath is a screenshot of what the World's land and oceans could take looked like during the Terminal Glacial Maximum when bounding main level was about 125 meters below current bounding main level. You lot can run across the connecting land in southeastern Asia, Australia, between Europe and the UK and between Russia and North America.

Later the kickoff several hundred anxiety of sea-level drib, the adjacent major feature is the appearance of the oceanic ridges. These ridges are strings of volcanoes formed from the splitting of oceanic crust in the center of the Atlantic and Pacific Oceans, amid others.

Around 6,000 feet of ocean draining reveals near of the bottom of the ocean. Even so, there are nevertheless over 4,000 anxiety of ocean to bleed, the last drop from the Marianas Trench, which sits at a depth of 10,911 meters.

While there is no concern that the oceans will bleed anytime shortly, the idea exercise reveals interesting features that our ancestors faced and can assist us make sense for early human migration as well as what we could face if another ice age began.

Thankfully, nosotros accept a while to go before worrying near our oceans really drying up.
