26. 12. Top soil has a rough texture with spaces between the grains. This allows water to filter quickly through the soil. Clay soil, however, is composed of smoother particles that stick together with little or no spaces between. What would happen if clay were used as a water filtration method? The water –Awould flow freely through the clay.B would not flow easily through the clay.C in the clay would evaporate very quickly.D would change the clay into sedimentary rock.
