In absence of gravity there would be no atmosphere, no pressure, no liquid water and especially no flowing liquid water.

You obviously have to balance the water pressure and temperature to reach slow ice formation, and maybe you need a more interesting container shape than a donut to get interesting results.
- lmilcin 7y agoWell, in space water starts to boil away immediately so you would need a gas tight container which don't typically happen in nature in sizes that would allow internal currents to develop.
- wongarsu 7y agoEarth is a (reasonably) gas tight container filled with flowing liquid (lava propelled by convection currents). Europa (the moon) is a reasonably gas-tight container filled with water under an ice sheet. Of course Earth also has appreciable gravity. The real problem isn't that nature produces no gas tight liquid-filled containers, it's that gravity is the primary mechanism by which things are naturally created in space. Asking for a situation without gravity virtually requires artificial construction.
