What force pushes groundwater from pore to pore below the water table?

Question

Quizplus · Accepted Answer

The hydraulic gradient is the force that drives the movement of groundwater from pore to pore below the water table. It represents the difference in pressure between two points in the subsurface and determines the direction and rate of groundwater flow. This force is directed down-gradient, meaning that groundwater will naturally flow from areas of higher potential to areas of lower potential.
