What part does gravity play in the function of the water clock?

.I kind of don't understand this question. All I need is a better understanding

Gravity plays a crucial role in the function of a water clock. A water clock, also known as a clepsydra, is a device that tells time based on the flow or displacement of water. It operates on the principle that water always flows from a higher point to a lower point due to the force of gravity.

In a typical water clock, water is allowed to flow slowly from a container through a small opening or tube into another container below. As the water accumulates in the lower container, it indicates the passage of time.

Gravity is responsible for regulating the flow of water in the clock. The gravitational pull causes the water to flow downward, creating a steady and consistent flow rate. The height difference between the upper and lower containers determines the speed at which the water flows. By controlling the size of the aperture through which water flows, the water clock can be calibrated to measure time based on the desired flow rate.

In summary, gravity ensures the constant and controlled downward flow of water in a water clock, enabling it to measure the passage of time.
