The ocean without water??

Question

I've always wondered that question... and if anyone could find a pic on the internet of this., could you please post a link to it??

That would be scary to walk on the coast of the USA. say Texas for example and look out at the sea and see nothing but a 3-4 mile deep hole... kinda scary if you ask me.

Answer 1

it's right underneath the sky without air.

seriously, before long, the Aral Sea is going to be just that.  Google it for a nickel's worth of education.

Answer 2

Interestingly, we know more about the surface of Venus than we do about the surface of the ocean because its difficult and time-consuming to map. It wouldn't just be a big hole, it would be a system of valleys and ridges similar to the regular surface, just at a lower level.

Here's a pic of the main relief features of the ocean floor across the world. You can see the mid-ocean ridges quite clearly:
