Oceans held on by gravity
Human can jump off earth surface why?
Because our legs can generate more force than gravity by pushing down. Once you lift off you aren't pushing against gravity anymore and so you slow down, and then get pushed back to the ground.
Gravity depends on your mass, so the ocean is experiencing millions of times more force than your body is, because it has millions of times more mass.
