I am obsessed with deep sea documentaries, just OBSESSED! Know anything cool about the ocean, buddy ol' pal?
Why yes.  I am an Oceanography major.  On our planet, the ocean makes up much of the hydrosphere.
How much of the hydrosphere, exactly? I think I've heard of that before!
Our oceans account for 97.5%
HOLY CHEESEBALLS THATS A LOT! How deep is the ocean?
Well, that varies depending on where you measure.  It's total volume is 1.35 billion cubic kilometers!
