Question 1.
What is soil description?
Show hintHide hint
Think of characteristics like color and texture.
Question 2.
What does the effective size (D10) indicate?
Show hintHide hint
Look at where the curve intersects.
3Question 3.
What is the primary purpose of soil classification?
- To describe the color of the soil
- To group soils with similar behavior
- To determine the soil's planting capacity
Show hintHide hint
Consider how engineers would approach differing soils.
4Question 4.

- True
- False
Show hintHide hint
Think about the sieve sizes defined in the section.
Question 5.
Given a soil sample measuring D10 = 0.02mm and D60 = 0.3mm, calculate the uniformity coefficient, and explain what this indicates about the soil.
Show hintHide hint
Apply the uniformity coefficient formula.
Question 6.
A grading curve for a sample shows a high percentage of clay with low effective size. Discuss the potential engineering challenges this might pose.
Show hintHide hint
Investigate the behaviors of clay in construction scenarios.
