Question

what is percolation? how does composition of a soil affect the rate of percolations?​

Answer 1

$\large\fbox\red{Answer}$

In physics, chemistry and materials science, percolation (from Latin percolare, "to filter" or "trickle through") refers to the movement and filtering of fluids through porous materials.

The process in which water passes down slowly through the sol is called percolation of water. But water does not percolate at the same rate in all types of soils. Sandy soil allows maximum percolation of water and clay soil allows minimum percolation of water.

Answer 2

Explanation:

Percolation in soil is simply the movement of the water through the soil and a soil percolation test is the means to measuring this movement. It is related to both saturation and water that drains away from roots too rapidly.

Soils containing large proportions of sand have relatively large pores through which water can drain freely. These soils are at less risk of producing runoff. As the proportion of clay increases, the size of the pore space decreases. This restricts movement of water through the soil and increases the risk of runoff.
