Question 1.
What happens to permeability as soil density increases?
Show hintHide hint
Think about the void spaces in the soil.
Question 2.
Is dry-compacted soil generally more or less permeable than wet-compacted soil?
Show hintHide hint
Consider the moisture's effect on soil structure.
3Question 3.
What effect does increased dry density have on soil permeability?
- A. Increases permeability
- B. Decreases permeability
- C. No effect
Show hintHide hint
Think about the spaces in packed soil.
4Question 4.
True or False: Soil compacted wet of optimum is always less permeable than dry compacted soil.
- True
- False
Show hintHide hint
Reflect on the differences in soil structure.
Question 5.
Given a soil sample with varying moisture content, predict how permeability would change across four compaction scenarios.
Show hintHide hint
Consider how each moisture level impacts compaction.
Question 6.
Design an experiment that examines the effect of particle size on compaction and permeability.
Show hintHide hint
Different sizes will yield different permeabilities, so prepare to record observations.
