As the soil particles become smaller, their water-holding capacity increases, as each soil particle is surrounded by a film of capillary water. This water is very effective in the decomposition of the soil particles. Hydration, oxidation and carbonation work simultaneously. These decomposition processes are always accompanied with increases in bulk and these tend to disrupt the rock and further assist to disintegrate it.
