Answer 1

Gravity attracts matter, so matter goes where gravity is stronger (if the matter is able to move there, which liquid water in an ocean is). Just like iron filings will pile up on top of a strong magnet, water will pile up on top of an area with stronger gravity (and thus avoid areas with weaker gravitational pull).
