When you look at the soil, it’s not like concrete with no holes or anything like that, it is continuously reworked by animals that live in the soil, by the plant roots, by drying and wetting up, or freezing and thawing, it sort of breaks the soil up, so the water can get into that soil through pores at the surface.
