percolation
(noun)
the seepage or filtration of a liquid through a porous substance
Examples of percolation in the following topics:
-
Physical Properties of Soil
- In this area, rainwater percolates through the soil and carries materials from the surface.
-
The Water (Hydrologic) Cycle
- Rain eventually percolates into the ground, where it may evaporate again (if it is near the surface), flow beneath the surface, or be stored for long periods.
-
Freshwater Biomes
- Bogs usually occur in areas where there is a clay bottom with poor percolation: the movement of water through the pores in the soil or rocks.
