What if ...

all the oceans were drained from planet earth? Interesting concept eh? :)

These days the concern may be more about what Earth would look like if all the ice melted – but this look at what we'd see if all the oceans drained away is seriously fascinating.

Now of course, all the oceans can't exactly drain away – where would they go? We have a specific amount of water on the planet, it just moves around in different phases to different places. But it used to be that there was less water in the oceans, back when it was locked up in ice on the land.

In 2008, NASA physicist and animator Horace Mitchell created a video showing what the planet would look like if all the oceans slinked away. More recently, former NASA planetary scientist James O'Donoghue gave the video an update. He tweaked the speed a bit and added depth tracking to show levels.

Cool without question.
