Porosity

Which should have the greatest capillarity based on sediment size?

• A
• B
• C
• D

Which container has the lowest porosity?

• A
• B
• C
• A and B

Which statement is true based on the above image?

• C is the most permeable
• A and B have the same porosity
• B would have the highest capillarity
• Water would infiltrate the slowest in B

What variable is the same between all three containers?

• Porosity
• Permeability
• Capillarity
• Infiltration Rate

Why does D have a lower porosity than the rest?

• It has bigger sediments
• It has rounded sediments
• It is poorly sorted
• It is loosely packed

Porosity refers to...

• the shape of the particles
• The sorting of the particles
• % of pore space in a material
• % of cement in a material

Poorly sorted soil...

• has low porosity
• has high porosity
• has high pore space
• means water will move through quickly

Well sorted soil...

• has low porosity
• has low pore space
• has high porosity
• means water will move through slowly
