that would impact sampling activities.
9. Using diagrams and words describe the various layers of loose material on the
Earth's surface.
10. In the diagram in question 9 where would the capillary fringe be located?
11. A soil bulk density sample is taken. The ring containing the soil has a diameter of 6
cm and a height of 3 cm. The soil plus ring weight is 114.9 g, and the ring weight is 15 g.
Determine the bulk density of this soil and its percentage solid portion and percentage
void space.
12. Describe the relationship between atmospheric air and soil air.
13. What is the effect of plants on the infiltration of water into soil?
