Chapter 28, Problem 5RQ

To determine

The types of soil that allows the greatest amount of rainfall to soak in them.

Answer to Problem 5RQ

The soil which allows the greatest amount of rainfall to soak in is sandy and loamy soil.

Explanation of Solution

The amount of rainfall or water that can be soaked or absorbed by the ground depends on the surface's permeability and porosity. The porosity of the soil varies on the size, shape, and packing of the particles. It means that a soil having greater sized particle will have greater porosity as compared to others. It is the measure of the maximum amount of water at a given spot.

On the other hand, permeability is a porous substance's ability to permit the flow of fluid. When these pores have good porosity and are connected properly to each other, it results in better movement of liquid through it. Soils like sand and loamy have better connections between the pores, which allow them to soak rainfall water more efficiently.

Conclusion:

Therefore, the soil which allows the greatest amount of rainfall to soak in is sandy and loamy soil.
