Which sample has the GREATEST porosity?

• sorted

• unsorted

Which sample has the LEAST porosity?

• tight pack

• loose pack

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

What does this picture illustrate?

• porosity because it has holes, permeability is the flow of water

• permeability because it has holes, porosity is the flow of water

Soil with the greatest porosity has particles that are

• poorly sorted and tightly packed

• poorly sorted and loosely packed

• well sorted and tightly packed

• well sorted and loosely packed

Which of the following statements is the definition of permeability?

• the amount of air space between sediments

• the ability of water to flow through sediments

• the density of sediments

• the infiltration rate

Which sample is MOST permeable?

• round

• flat

• oval

Which sample is LEAST permeable?

• round

• oval

• flat
