Answer 1

It’s the composition of the soil that allows for infiltration of water. The particle size of sandy soils is larger than that of clays and silts. The voids created by these larger particles allow water room to travel. Clay and silt have much smaller particles and greater cohesion so it becomes a solid layer blocking the water.
