Porosity

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

Well sorted soil...

• has low porosity

• has low pore space

• has high porosity

• means water will move through slowly

Base your answer to the following question on the diagram, which represents samples of soil and bedrock at Earth’s surface.  The arrows represent possible infiltration of rainwater   Which sample probably has the greatest porosity?

• Granite bedrock

• Pebble-and-sand soil

• Pebble soil

• Conglomerate bedrock

Which should have the greatest capillarity based on sediment size?

• A

• B

• C

• D

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

Poorly sorted soil...

• has low porosity

• has high porosity

• has high pore space

• means water will move through quickly

These containers have the same volume of beads which are representing soil particles. What is the relative porosity and permeability of each?

• The container on the left has the higher permeability and porosity

• The container on the right has the higher permeability and porosity

• The container on the left has the higher permeability, but they both have the same porosity

• The container on the right has the higher permeability, but they both have the same porosity
