The phenomenon of the movement of water through the soil is termed as _____.

Percolation is the process by which water moves through soil or other porous materials due to gravity. When it rains or water is applied to the surface of the soil, it infiltrates the soil and begins to move downward due to the force of gravity. As the water moves through the soil, it may encounter obstacles such as rocks or dense clay layers, which can slow down its movement or cause it to move laterally.

Hence, the phenomenon of the movement of water through the soil is termed percolation.
