Solution:
The above statement is true.Percolation is the movement of the water through the soil itself. Finally, as the water percolates into the deeper layers of the soil, it reaches groundwater, which is water below the surface.
The downward movement of soil moisture through a zone is called the vadose zone. The vadose zone is located between the root zone and the capillary fringe of the groundwater table. The other name which is given for percolation is ‘ internal drainage’.
