Answer:
Clay particles in the soil may swell as they become wet and thereby reduce the size of the pores. In areas where the ground is not protected by a layer of forest litter, raindrops can detach soil particles from the surface and wash fine particles into surface pores where they can impede the infiltration process.

Answer:
As explained below.
Explanation:
- Porosity or a void fraction is the measure of the spaces between the matter and as a fraction and measured from 0 to 1 or as a percentage of 100. There are ways to test the porosity by the CT scanning techniques, hydrologic conductivity and the porosity of rocks like the sandstone, shale, and granite have more complex property as compared to the alluvial sediments.
- Thus infiltration is concerned with the water and the rock type, the pore distribution, the cementation, the diagenetic history, and the composition, and not controlled by the grain size as the volume between-grain space is related to the method of grain packing.
- As the porosity of the surface soil gradually decreases the particle size starts to gradually increase.
