Question 1.
What is the purpose of wet sieving?
Show hintHide hint
Think about what happens when you wash soil.
Question 2.
Why don’t we use dry sieving for particles smaller than 75 microns?
Show hintHide hint
Consider how small particles behave when dry.
3Question 3.
What is the main purpose of wet sieving?
- To dry soil samples
- To separate fine grains
- To measure soil temperature
Show hintHide hint
Consider which method focuses on separating sizes.
4Question 4.
True or False: Sedimentation analysis is used for soil particles larger than 75 microns.
- True
- False
Show hintHide hint
Recall the size limits for each analysis method.
Question 5.
Given a soil sample, set up a wet sieving and sedimentation analysis process and analyze how to combine results into a grading curve.
Show hintHide hint
Ensure you understand how to convert measurements into cumulative percentages for graphing.
Question 6.
Evaluate how varying the amount of water affects the effectiveness of sedimentation in calculating particle sizes.
Show hintHide hint
Consider viscosity and how it impacts settling speed!
