In village water supply, which structure stores potable water and uses gravity for distribution?

• A. Water Tower
• B. Windbreak
• C. Weathering
• D. Well

Answer: (A)

This question tests understanding that using height to create water pressure is a simple, gravity-driven way to store and distribute potable water. A water tower is an elevated tank that holds treated drinking water. Because it sits high above the ground, gravity pushes the water down through the distribution pipes to homes and buildings, providing pressure without constant pumping. This setup is particularly practical in villages, keeping water available even when demand varies.

Windbreak, weathering, and well don't fit this description. A windbreak is a line of trees to block wind, weathering is the breakdown of rocks, and a well is a groundwater source rather than an elevated storage and gravity-fed distribution system.
