The tides.
In a vacuum, a balloon with helium (for example) would also fall down. The point is that gravity pulls on the surrounding air with more force, because it is heavier; this pushes the balloon up. The situation is similar to a boat floating in water. The water displaces the boat - pushing it up precisely because of gravity.

No, not directly ... it needs gravity to be present, but gravity alone won't do it. There's plenty of gravity on the moon, but a helium balloon won't rise there. A helium balloon floats in air, for exactly the same reason that a block of wood floats in water. Look up "Archimedes' Principle" and read about it.
That sounds like a "hovercraft", which doesn't rise or fall, but just exactly hangs there.If the vehicle expels a gas with a force GREATER than the pull of gravity ... like a rocket for example ...then it can actually rise.
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them.

Tide.
The tide
Because of gravity.
he proved that there was a force called gravity. the moon's gravity causes water to rise.
Tides
Tides are the rise and fall of ocean water. They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth.
The rise and fall of lake michigan's water, and any other lake or ocean is called a wake.
because of gravity. the paper will not actually fall onto the moon but rise up. earth has 10.0n of gravity and the moon has much less, so it wont fall but rise.
The rise and fall is the tides.
The cyclical rise or fall of the waters of the ocean is called tide. The tides are caused by the attraction of gravities of the moon, sun, and Earth
