* Artesian Well: An artesian well relies on pressure from a confined aquifer, which is created by gravity pulling water downhill and into the aquifer.

* Hillside Spring: Springs form when groundwater flows naturally to the surface, usually due to gravity pulling the water down a slope.

* Water Table: The water table is the upper surface of the saturated zone, where water fills the pores of the soil. Gravity plays a crucial role in the movement of water and the formation of the water table.

* Capillary Fringe: The capillary fringe is the zone above the water table where water is drawn upward by capillary action. This action is caused by the surface tension of water and the attraction between water molecules and the soil particles. Gravity actually works against the capillary fringe, as it pulls water downward.

In summary: Gravity is essential for the formation of artesian wells, hillside springs, and the water table. The capillary fringe, however, forms due to capillary action, which is independent of gravity.
