you use the suction force from your mouth and it flows upward
s an arrangement, as in Figure 3, in which the air flows upward through the fill and the water flows downward through the fill.
simply, a pen writes as the ink flows down through its nib. the force of gravity is the only thing (in general circumstances) that pulls the ink out. i.e. no gravity, no flow of ink and no writing!
This is a system where the boiler heated fluid flows by the principle of gravity-flow instead of pumps. This principle requires the distribution system to be sized correctly and installed with accurate slopes for the hot water to rise in and flow to the terminal units.
Gravity ! The source (or start) of a river is (usually) high up in a mountain or hill. As the water travels downhill, it combines with others - gradually widening and gathering pace.
Of course not, there is gravity on earth.
When a siphon flows the wrong way.
The river does not flow upwards. The Earth is round, the Nile simply flows South to North - on a map it just looks like it flows "upward"
Usually, there are only small portions of a river that flows against the slope of the land , or gravity. I work at a park on the White River in Hamilton County IN. We are in a huge bend in the river and the White River flows northward at this point, against the slope for about a 1/4 of a mile. This happens on the St. Joseph River in northern Indiana and a co-worker tells me the Cuyahoga in Ohio also has this phenomena. I reckon it is an uncommon, but not rare, situation.

Water flows downwards due to Earth's gravity.
water flows down hill because of gravity

Due to capillarity, oil flows upward in the lantern. The attraction of liquid molecules in the oil between each other and with the wick is known as capillarity.
Upward communication is the natural direction that information flows in an organized structure from the bottom to the top with no or little message distortion.
