The diagram below shows a laboratory setup. The rubber band holds filter paper across the base of the open tube to hold the soil sample. The tube was placed in the water as shown. The upward movement of water is represented by arrows. The height of the water that moved upward within the soil was measured. Students repeated this procedure using soils with different particle sizes. Results of the experiment are shown in the data table.

Results of this experiment lead to the couclusion that
(1) capillarity is greater in soils with larger particles
(2) capillarity is greater in soils with smaller particles
(3) permeability is greater in soils with larger particles
(4) permeability is greater in soils with smaller particles

(2) low density and is felsic
(3) high density and is mafic
(4) high density and is felsic
